Use the registry entries that vsvars32.bat uses to detect the location of
MSBuild.exe in the framework directory. Invoke MSBuild with the option
/p:VisualStudioVersion=$version
so it knows from which VS version to load the system build rules. Teach
cmGlobalVisualStudio11Generator to set its ExpressEdition member using the
registry.
Add WDExpress to the list of registry search locations. Add VS 11 to
the list of VS versions and corresponding generator names. Fix the
search logic to use the most recent version found under any registry
entry.

The logic added in commit e1c89f08 (file(DOWNLOAD): Add options for SSL,
2012-08-21) did not actually provide the documented behavior. Simplify
the implementation to read the variable values first and then replace
them with the explicit argument values if encountered. Always set the
curl option CURLOPT_SSL_VERIFYPEER to either on or off explicitly
instead of depending on the curl default behavior.
TLS has superseded SSL so rename the recently added file(DOWNLOAD) and
ExternalProject options using the newer terminology. Drop "CURLOPT"
from names because curl is an implementation detail.
Extend the number of components tested by
if(... VERSION_LESS ...)
if(... VERSION_EQUAL ...)
if(... VERSION_GREATER ...)
from 4 to 8. The latter is a more extreme maximum.
Add the ability to request that downloads disable or enable Certificate
Authority checking with https ssl downloads. When the option to verify
the servers CA is disabled, one may verify download contents with SHA
hashes.

Fix the name of the member variable.
If a section has subsections (ie. subelemens with a title), all elements
before the first title are written inside an <abstract>. Also wrap
<programlisting> in <para>, to allow preformatted output in abstracts.
The DocBook formatter used to generate something like:
<para id="section"><sect2><title>Title</title></sect2>Some Text</para>
Which was completely wrong. In DocBook, a section should look like this:
<sect2 id="section"><title>Title</title><para>Some Text</para></sect2>
Attributes in XML may contain alphanumeric characters, underscores,
colons and dots. When DocBook is chunked, the dot is often used as a
path separator. To generate a valid ID, we take the title of the
section, transform all non-alphanumeric characters to underscores and
then add a prefix separated with dots. We also add the document name as
a prefix, in order to 'xinclude' eg. cmake.docbook and ctest.docbook in
the same document. IDs are written in multiple places, so the code is
factored to a function.
When DocBook is transformed (eg. to PDF, HTML, ...), a TOC is generated
from the document's layout. The TOC-like list that the docbook
formatter used to generate was both redundant and invalid.
Sometimes it wasn't returning an error and one could continue
with the generate generate as if no errors occurred, and even
with an incomplete configure step.
This call 'svn status' and parse the result to get the list of externals
repositories. The external repositories found are added to the
Repositories list.
- Suppress the URL, Root, Base fields from the cmCTestSVN class
- Update the code to use RootInfo instead
- LoadInfo(), GuessBase(), and a new LoadRevision() functions work on a given SVNInfo
- Use the implementation from the base class for LocalPath(), correct path is built by SVNInfo::BuildLocalPath() instead
The Repository list will contain the SVNInfo of all the repositories
(root and external ones). The RootInfo pointer will point to the
SVNInfo structure of the root repository.
The POSITION_INDEPENDENT_CODE property documentation states that its
default value depends on whether SHARED or MODULE is given to the
add_library call. Since these are options to the add_library command we
should document on the command how they affect the property.
While at it, add a missing space to the POSITION_INDEPENDENT_CODE
property documentation.

7ae4479 -fix line length
87fe428fix#13474: also rescan dependencies if the depender does not exist
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use. The
method of detection and the exact results store varies across CMake
versions as things improve. This leads to problems when loading files
configured by a different version of CMake. Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files. This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).
Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version. Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake. Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.
Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose. The new variable points
at the version-specific directory while the old variable did not.
Several more recent Visual Studio Express editions are now available and
they support debug builds. Simplify our VS platform files by removing
support for these old tools. If anyone still uses them we can restore
support with a more modern way to test for them.
When a language is not enabled at the top level of a project but is
enabled in multiple disjoint subdirectories we should re-use the
CMake<lang>Compiler.cmake file from the first directory. Load the file
whenever it exists and is not left from a different version of CMake.
Run cmparseMSBuildXML.py on cl.xml, lib.xml, and link.xml to generate
our flag tables:
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/cl.xml" > cmVS11CLFlagTable.h
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/lib.xml" > cmVS11LibFlagTable.h
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/link.xml" > cmVS11LinkFlagTable.h
Fix up the declaration names at the top of each file. Finally, teach
cmVisualStudio10TargetGenerator to select the version of the table
matching the version of VS.
In VS 11 the WindowsAppContainer element enabled by the
VS_WINRT_EXTENSIONS property activates precompiled header support
automatically if no PrecompiledHeader setting is specified. For VS 10 and
11 set PrecompiledHeader to "NotUsing" explicitly by default unless
overridden by a project-specified flag.
Suggested-by: Eugene Golushkov <eugene_gff@ukr.net>
Since commit 9e01aefd (VS: Add support for WinRT project properties,
2012-02-03) CMake generates for VS 11 projects the 'Immersive' element
for the VS_WINRT_EXTENSIONS target property. That was based on the VS
11 preview version. The final version renamed the element to
'WindowsAppContainer', so generate that instead.
Suggested-by: Eugene Golushkov <eugene_gff@ukr.net>
Otherwise, CTEST_USE_LAUNCHERS can be set to true in a driving ctest
script, and everything looks like it would work and reports 0 build errors,
but actually there can be any amount of errors and they are just not reported.
By adding this check cmake now errors out if CTEST_USE_LAUNCHERS is enabled, but
the RULE properties are not set, which would lead to a not-working ctest run.
Alex
There is no need to do so. Be consistent with include directories and
ensure uniqueness.
This requires changing the API of the cmLocalGenerator::AppendDefines
method, and changing the generators to match.
The test unfortunately can't test for uniqueness, but it at least verifies
that nothing gets lost.

directory where the project file is located (${CMAKE_BINARY_DIR}), which can
happen e.g. for EXECUTABLE_OUTPUT_PATH and related variables.
Now, it seems this code never worked.
If EXECUTABLE_OUTPUT_PATH was set to point into a subdir of CMAKE_BINARY_DIR,
the code did nothing.
If it pointed directly at CMAKE_BINARY_DIR or some other location, it created
a linked resource. I tested this with Eclipse Europa (3.3) and Juno (4.2), and in this
case both versions of Eclipse complained that this is a bad location for a linked resource.

...comparison operator in the IF command. In the event of
a tie, we intentionally return "true" so that dependent
build operations are guaranteed to occur until one file

A tie means we're not sure, so return true to be on the
safe side.
SORT, REVERSE, and REMOVE_DUPLICATES can only operate on exactly one argument.
Until now all other arguments were silently ignored. Give an error instead.
This expression evaluates to '1' or '0' to indicate whether the build
configuration for which the expression is evaluated matches tha named
configuration. In combination with the "$<0:...>" and "$<1:...>"
expressions this allows per-configuration content to be generated.
Add generator expressions that combine and use boolean test results:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
These will be useful to evaluate (future) boolean query expressions and
condition content on the results. Include tests and documentation.
Since commit 77543bde (Convert CMake-language commands to lower case,
2012-08-13) the CMakeVersion.cmake file contains lower-case 'set'
commands. Teach CMakeVersion.bash to replace the lower-case name
instead of the old upper-case 'SET'.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'

Multiple versions of Xcode may be installed in different locations.
Run "xcode-select --print-path" to detect the active Xcode location
and parse its Contents/version.plist file. Note that the Xcode.app
directory name may vary in developer versions.
In cmGlobalXCodeGenerator::Generate we generate a .xcodeproj for each
directory in the tree containing a project() command. First we
iteratively use SetGenerationRoot to add "ALL_BUILD" and other targets
to each project. This leaves "CurrentProject" set to the last project
when we invoke cmGlobalGenerator::Generate, which is not the same as the
top-level project if any subdirectories invoke the project() command.
When cmGlobalGenerator::Generate reaches CreateGeneratorTargets it
constructs cmGeneratorTarget and calls ComputeTargetObjects exactly once
per target. In this context the value of CurrentProject is undefined so
we cannot pass it to GetObjectsNormalDirectory. Use "$(PROJECT_NAME)"
instead so it will adapt automatically to each project.
Also teach Tests/ObjectLibrary to cover this case.

Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=680825
A common mistake is to write
macro(foo arg)
if(arg)
endif()
endmacro()
and expect if() to treat "arg" as a variable. The documentation of the
macro() command already states that arguments are not variables, but
users writing the if() command may not look at the macro() docs.
Add a note to the if() documentation.
The work around is only needed by older GCCs (only testet 4.4/4.7)
Ninja is very new so chances are high that there is also a new mingw.
Use slashes in link rsp file, because ar.exe can't handle \.
Previously CMake silently accepted the empty string and added a bogus
dependency on the current directory. Instead warn about the empty file
name and ignore it. We cannot make this an error because there may be
existing projects that accidentally depend on the old behavior.
Add a RunCMake.include test to cover this case.

Since commit e1409ac5 (Support building shared libraries or modules

Clang tooling requires that paths in the directory and file JSON
fields are relative to the directory field, but clang doesn't normalize
the paths already. The result is that clang doesn't find the relevant
entry for files which begin with ../.
When linking with cmake and vs_link_* the command line
could be too long for cmd.exe, which needs not to be
called in this case. (was not cached by a test)
Introduce rules which don't use the shell and use this
rule when there are no pre or post step.
For free we get a small speedup, because cmd is then
not called.
Also be more accurate when estimating the
command line length.
All tests are passing as of this morning on the CMake dashboard in

Nice job to all the Ninja+CMake contributors. Congrats!
rc.exe doesn't support /showIncludes.
Because .rc files also #include stuff we can

Done one the fly by cmcldeps.
Windows and Apple machines have predominantly used case-insensitive
filesystems so our file(INSTALL) command uses case-insensitive pattern
matching. It is implemented by converting the pattern and file path to
lower case before matching. The FILES_MATCHING option is implemented by
excluding a path that does not match any pattern unless it is a
directory that must be searched recursively. However, the test that an
excluded path is a directory is executed on the lower-case path and
therefore fails on mixed-case input paths on case-sensitive filesystems.
Fix the file(INSTALL) implementation to use the lower-case path only for
pattern matching and preserve the original path for tests against the
real filesystem.
bd34963 Refactor generation of shared library flags
55d7aa4 Add platform variable for flags specific to shared libraries
31d7a0f Add platform variables for position independent code flags
Older C++ compilers do not provide a standard std::stringstream.
Use our compatibility interfaces instead.
Also avoid std::stringstream(openmode) signature. Our approximate
stringstream implementation provided when the standard one is not
available does not support the openmode argument.
CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a
variety of purposes that are correlated with shared libraries but not
exclusive to them. Refactor generation of these flags to use new
purpose-specific platform variables
CMAKE_<lang>_COMPILE_OPTIONS_DLL
CMAKE_<lang>_COMPILE_OPTIONS_PIC
CMAKE_<lang>_COMPILE_OPTIONS_PIE
Activate the DLL flags specifically for shared libraries. Add a new
POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and
default to true for shared libraries to preserve default behavior.
Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to
allow easy global configuration in projects.
Although the default behavior is unchanged by this refactoring, the new
approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely. We must
leave it set in case projects reference the value. Furthermore, if a
project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new
value to be used. Add policy CMP0018 to handle compatibility with
projects that modify this platform variable.
Add a PositionIndependentCode test on platforms where we can get
meaningful results.
When global property TARGET_SUPPORTS_SHARED_LIBS is FALSE we should
still allow OBJECT libraries. This was an oversight in commit b87d7a60
(Add OBJECT_LIBRARY target type, 2012-03-12). While at it, fix the
warning message to report context.
cmcldeps wraps cl and adds /showInclude before calling cl.
It parses the output of cl for used headers, drops system
headers and writes them to a GCC like dependency file.
cmcldeps uses ATM ninja code for process handling,
but could be ported later to SystemTools.
TODO: Why needs ninja multiple calls in the BuildDepends test?
Since commit c8ef6430 (Allow directory names containing '=' and warn if
necessary, 2012-02-06) we allow directories with '=' instead of
rejecting them as was previously done since commit 8704525f (Reject
directory names containing '=', 2011-01-14). However, we did not warn
in all cases that '=' may cause failure, such as when it appears on the
right-hand side of a dependency line.
Both commits above were made assuming that '=' cannot be escaped in Make
syntax, but it can be achieved with a variable:
EQUALS = =
left$(EQUALS)side : right$(EQUALS)side
Use this approach to escape '=' in dependency lines, thus supporting
the character in paths.
All our tests now pass when CMake is built in source and build trees
both containing '=', except for the "OutOfSource" test. It fails in
its coverage of the obscure "OutOfBinary" test case where part of the
build tree is located outside the main build tree of the test. The
reason is that CMake must invoke a command like
$(MAKE) -f /path/with=sign/build.make /path/with=sign/somefile
but the make tool interprets the last argument as a variable assignment.
This is an acceptable limitation, since the case is so obscure, in
exchange for supporting '=' cleanly otherwise.
When reading archive entries from disk strip any "fflags" entry headers
that may have been loaded from the filesystem when libarchive is built
with HAVE_STRUCT_STAT_ST_FLAGS (struct stat has 'st_flags'). The local
filesystem flags are not useful for distribution. Furthermore, GNU tar
does not understand the "SCHILY.fflags" extended header used to store
the flags in the archive. Use the approach from commit e8558efa
(cmArchiveWrite: Clear xattr and acl from entries, 2011-04-07) to remove
the flags and avoid producing the non-portable extended header.
When MinGW is used slashes are used for dependencies
because ar.exe can't read rsp files with backslashes.
Many thx to Claus Klein for starting working on this.

6ba055b CPack add easy possibility to warn about CPACK_SET_DESTDIR
Commit "KWSys: Fix SystemTools environment memory handling" (2012-04-26)
added a _WIN32 case inside !KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H to dllimport
the "environ" global. Howver, KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H is true
on every Windows toolchain we support so the case is never reached.
Furthermore, even if it were reached the use of dllimport is incorrect
because the toolchain might not be compiling with a dynamic runtime
library. Remove the unused incorrect line and supporting conditionals.
Fortran sources that pass through the C preprocessor may use
#include "header"
syntax or
#include <header>
syntax. CMake already follows the former. Teach it to follow the
latter.
More generally add the check for possible generator "activation" at
runtime depending on a generator specific check.
The dynamic behavior is currently implemented only for MacOS
and should be fully backward compatible for other system.

CMAKE_xxx vars are now used in the CMake-generated cmake_install.cmake
script while CPACK_xxx equivalent vars are used from within CPack.
CPack is responsible for getting/forwarding definitions of
CPACK_xxxx var corresponding to CMAKE_xxxx when invoking
CMake-generated install scripts.
As a consequence:
CMAKE_ABSOLUTE_DESTINATION_FILES
CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
may be used from outside CPack as well.
e.g.
cmake -DCMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION=1 -P cmake_install.cmake
works as expected.

The [usually] wrong usage of absolute DESTINATION in INSTALL rules
keeps popping-up on the ML. We shall have some way to:
1) easily detect it.
2) forbids this for some CPack generator like NSIS
In fact it should certainly be forbidden for *any* generators
when used on Windows but we may implements that on top of the current
patch.
The patch ask the task to the generated cmake_install.cmake scripts.
Those scripts are a little bit more complicated with that but
iff there are absolute DESTINATION. This cost nothing if relative
DESTINATION are used.
Two new vars are introduced (and documented to handle that):
CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
and
CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
Until now an unnamed component was always named "Unspecified".
Now this name is taken from the new cmake variable CMAKE_INSTALL_DEFAULT_COMPONENT_NAME,
which is initialized to "Unspecified". But it can now be set to something
project-specific, per directory

The coverage global should be in the local namespace. This means the global
will be ^ZZCOVERAGE instead of ^COVERAGE. Change the parser to look for ^ZZCOVERAGE
instead of the old ^COVERAGE
Header files listed in a target's PUBLIC_HEADER or similar properties
are marked as OS X Framework content. Refactoring performed by
commit 11d9b211 (Add cmGeneratorTarget to represent a target during generation, 2012-03-07)
commit 45c2f932 (Simplify cmMakefileTargetGenerator using cmGeneratorTarget, 2012-03-07)
commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source classification, 2012-03-19)
and related commits accidentally removed such files from treatment as
normal header files by the VS generator (generators other than Makefiles
and Xcode). Move handling of such files out of cmGeneratorTarget and
back to cmMakefileTargetGenerator. The central cmGeneratorTarget
classification will always treat them as header or extra sources.
The hash_fun.hxx header is configured whether FundamentalType is enabled
or not and so cannot depend on it. Run the relevant platform tests
whether or not FundamentalType is on and configure the result directly
into hash_fun. While at it, remove the dependence of SystemInformation
on FundamentalType too since it needs only information that we now
always compute.

Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it. This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.
Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it. Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.
The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders. Final substitution is
performed by ninja at build time. Therefore we cannot conditionally
replace the soname placeholders on a per-target basis. Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME. Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.
Since commit ed0075bd (Use relative paths for custom command inputs,
2011-06-22) CMake generates full paths to source files in VS 10 project
files to avoid trouble with deep source/build tree paths. However, the VS
10 IDE will not populate the source file property dialog for a file
referenced by full path. Instead use a relative path when possible. When
not possible produce a detailed warning explaining the problem and
suggesting use of shorter directory paths.
CMake <= 2.8.4 generated VS 10 project files with a relative path to
source files. Then commit ed0075bd (Use relative paths for custom command
inputs, 2011-06-22) switched to using relative paths only for source files
holding custom commands and full paths for other sources. This behavior
was inhereted by the VS 11 generator but is not needed so use the
workaround only for exactly VS 10. Explain the behavior in comments.
Most CMake generators produce relative paths within the build tree and
full paths to files outside the build tree. Make VS 10 and VS 11
project files consistent with this approach except for paths forced to
be relative to work around a VS 10 bug.
Remove the duplicate source file classification logic used to generate
the filter files. Instead record during the main vcxproj file
generation the source files generated for each tool. Also record
whether or not each source file is converted to a relative path. Use
the recorded result during filter generation to ensure consistency
between the project file and filter file.
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory. However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv. If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.
Replace use of putenv with setenv/unsetenv when available. The latter
manage internal copies of the values passed instead of referencing the
original memory. When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory. This requires an "unputenv" implementation. On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms. On other platforms fall back to direct
manipulation of "environ".
Also add UnPutEnv to the API and add a test for the behavior of both.
Generate anchors of the form
<a name="..."></a>
instead of
<a name="..."/>
to ensure browsers know that the anchor contains no text and do not try
to guess an end of the range. Also make the "section_Index" and item
label anchors empty instead of containing the section header or label
text. This ensures that the text associated with target anchors is not
rendered as if it were a hyperlink.
Since commit 4fbdce2b (try_compile: Use random executable file name,
2012-02-13) a different <target>.dir is used for each try-compile.
Cleanup the directories as well as their content to avoid accumulating
leftover temporary directories.

8217c26 Ninja: ensure output directories exist
KWSys is no longer shared in projects via a server-side directory
symlink in CVS. An automated nightly date stamp commit can no longer be
shared by multiple projects directly. It needs a per-project replay
robot so the nightly commits end up needing N+1 robots instead of N.
Remove the DateStamp feature because it is no longer useful or
maintained by nightly commits.
Replace use of AppendEnv/RestoreEnv pairs with instances of
SaveRestoreEnvironment. Simplify the signature of AppendEnv and use it
in place of similar loops elsewhere. Move the RestoreEnv implementation
inside the SaveRestoreEnvironment destructor which is the only place
left that calls it.
Move the CMake version number components out of "CMakeLists.txt" into
dedicated file "Source/CMakeVersion.cmake". Set the TWEAK level to the
date explicitly. Add a "Source/CMakeVersion.bash" script to update the
date, thus replacing KWSys DateStamp for CMake. Teach the bootstrap
script to extract the version components from their new location.
It seems that file.seekg(0) will, in some circumstances, cause the next
file.getline() to omit the first character it reads. Workaround the
bug by seeking from ios::beg explicitly.
Hide custom command .rule files inside the CMakeFiles directory. Ensure
a short, deterministic, and unique name by using a hash of the directory
path containing the output file. Preserve the file name so the entry in
the IDE is human-readable. Clarify the comment that explains why the
rule file must be created on disk.
Add cmGlobalGenerator::GenerateRuleFile to compute a generator-specific
rule file location. This will allow specific generators to override the
location of .rule files without changing the behavior of other
generators.
Teach cmMakefile::AddCustomCommandToOutput to return the cmSourceFile
instance to which the custom command is attached. Use the return value
instead of separately adding a .rule extension and searching for the
source. Mark CMake-generated .rule files explicitly with a property
instead of trusting the file extension.
When loading a find module or package config file the find_package
command defines several variables to provide information about the
caller's request. Previously this was documented only in the
Modules/readme.txt file which is not distributed. Document the
behavior explicitly in the main find_package documentation.
Since commit ed1ea24c (Fix INSERT to allow inserting to empty list,
2006-05-15) the list command allows insertion into an empty list at
index 0. Fix rejection of insertion at non-zero (negative) indices to
present an error message instead of crashing.
While at it, fix the error message of the GET and REMOVE_AT operations
when the list is empty to not present a bogus allowed range.
Add a "RunCMake.list" test to cover failure cases on empty lists.
Commit ffbe61bb (make sure english is used for output of gcov, 2008-05-10)
taught ctest_coverage to set LC_ALL=POSIX to get English output from gcov.
Use the more portable value LC_ALL=C and restore the original value when
finished.
This commit creates a dummy text file for each OBJECT library for
the CodeBlocks generator, so the generated project file can reference
a unique file for each target. Most probably these files are unused.

01e979a VS: Add CMakeLists.txt re-run rules at start of generation
9a2c60e Classify known header file extensions as headers
1c48992 Always compile sources with known language
Previously, we were setting the default configuration for a generated
Xcode project to the hard-coded string "Debug" even in cases where users
customized their configuration types such that the list did not contain
"Debug". Now, we use the first string listed in CMAKE_CONFIGURATION_TYPES
as the default config for generated Xcode projects.
Refactoring in commit a2514f15 (Simplify cmNinjaTargetGenerator using
cmGeneratorTarget, 2012-03-13) accidentally removed mapping of .def file
paths through ConvertToNinjaPath (via GetSourceFilePath). Take the
ModuleDefinitionFile value from cmGeneratorTarget and map it correctly
through ConvertToNinjaPath.
In addition to generating cleaner paths in the ninja build files this
correctly links up references to a generated .def file with the custom
command output that produces it.
Since commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source
classification, 2012-03-19) the VS 10 generator uses the
cmGeneratorTarget source classification instead of directly getting the
list of source files from the target. This accidentally dropped the
CMakeLists.txt files from generated projects because they are added too
late for cmGeneratorTarget.
All generator-specific source files must be added to targets prior to
cmGeneratorTarget construction. Refactor addition of the CMakeLists.txt
files with CMake re-run custom commands to take place before normal
generation begins, and therefore early enough to be included in the
cmGeneratorTarget classification.
Commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source
classification, 2012-03-19) introduced the first use of source
classification from cmGeneratorTarget (which originated as Makefile
generator logic) in a Visual Studio generator for handling of header
files. Fix classification of header files to match known header
extensions instead of only the HEADER_FILE_ONLY property. Make it
consistent with the "Header Files" source group.
Refactoring by commit 11d9b211 (Add cmGeneratorTarget to represent a
target during generation, 2012-03-07) and commit 45c2f932 (Simplify
cmMakefileTargetGenerator using cmGeneratorTarget, 2012-03-07) preserved
behavior introduced by commit 7740ccd1 (some cleanup of the makefile
generator, 2006-02-14) that favored the IgnoreFile extension test over
the availability of a known compilation language associated with a
source file. If a source is not marked as HEADER_FILE_ONLY and has a
known language extension or an explicit LANGUAGE property it should be
treated as that language. The LANGUAGE source file property
documentation says so.
9b32475 automoc: add define to test which caused bug #130182066511 automoc: fix#13018, proper cmake escaping to avoid false rebuilds
c652812 make cmLocalGenerator::EscapeForCMake() static
The variables stored in the AutomocInfo.cmake file were not properly
escaped, so when reading them back they could turn into lists, if they
contained double quotes initially.
This patch fixes this by using cmLocalGenerator::EscapeForCMake() to
escape the variables properly.

Patch by Amine Khaldi!
Also, start using the -MT flag to set a target name for depfiles.
This works around a bug observed in distcc, as explained in the
comment. Based on a patch by Alexander Usov.
Commit 9a6ff950 (Fix for bug where VS2010 did not use .obj files,
2011-04-01) assumed that if an external object is GENERATED that it is
the output of a custom command in the current target. If it is
generated by another target then VS will not automatically include the
external object in the current target. This bug was preserved by the
refactoring in the parent commit.
Instead use <None> for external objects generated by a custom command in
the current target and <Object> for all other external objects. Update
the ExternalOBJ test to cover this case.
Combine WriteCLSources and WriteObjSources into a single method. Use
the cmGeneratorTarget source classification to simplify tool selection
for each source file. Extend the classification to handle .idl files.

For example, when CPACK_<GEN>_COMPONENT_INSTALL and
CPACK_MONOLITHIC_INSTALL are both set. Previously, this
combination of variable settings produced an error without
any explanation. Now, in this case CPACK_MONOLITHIC_INSTALL wins
without trouble.
This is useful for when e.g. CPACK_ARCHIVE_COMPONENT_INSTALL is
globally on and one wants MONOLITHIC install for STGZ (but not
other generators). The same behavior may be obtained by re-setting
CPACK_ARCHIVE_COMPONENT_INSTALL to 0 but in any case the
'both set' case should have been handled without error.
Necessary for the Xcode generator, in which the CMakeLists.txt
files are added as sources merely for convenient access, without
any associated custom command.
Implement cmGlobalGenerator::ComputeTargetObjects in the Ninja generator
to pre-compute all the object file names. Use the results during
generation instead of re-computing it later.
Describe the OBJECT library signature of add_library and the
$<TARGET_OBJECTS:...> expressions needed to use object libraries.
Also document the what is not allowed for object library targets.
For now do not allow an OBJECT library to reference other object
libraries. Teach cmTarget::ComputeLinkImplementation to include the
languages of object libraries used by a target.
The write code introduced by commit 0b0d1b1d (add CMakeCache.txt
support, 2001-02-22) uses a temporary file but does not replace the
original atomically. Use cmGeneratedFileStream to do both
copy-if-different and atomic replacement.
Before, find_package in Config mode always set Foo_FOUND to true if the
Config file has been found and could be executed.
If the Config file itself detected some problem, like a missing dependency,
it did not have a way to signal to the outside that the package is not working.
With this patch, if a Config file sets Foo_FOUND to FALSE, this is taken into
account and not overridden.
Alex
Treat OBJECT libraries as STATIC libraries. The VS project file format
provides no way to avoid running the librarian so hide the resulting
.lib away next to the object files as it should never be referenced.
The object files will be left behind for reference by other targets
later.
This library type can compile sources to object files but does not link
or archive them. It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.
Diagnose and reject the following as errors:
* An OBJECT library may not be referenced in target_link_libraries.
* An OBJECT library may contain only compiling sources and supporting
headers and custom commands. Other source types that are not normally
ignored are not allowed.
* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
commands.
* An OBJECT library may not be installed, exported, or imported.
Some of these cases may be supported in the future but are not for now.
Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.
On machines where a usr/bin/packagemaker symlink is found, we were
unable to find the version.plist file relative to the symlink.
Resolve the symlink first, so we can find it relative to the
real PackageMaker.
