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.

to dictate the version or to detect the version by running the
command-line tool for NMake and Ninja generators. Drop configuration of
CMakeCPlatform.cmake and CMakeCXXPlatform.cmake from Windows-cl.cmake.in
because all the results it saved are now cheap to compute every time.
Until now it was only rerun if the compile definitions changed, but
of course it also has to rerun if the include dirs or moc options
change. Strange that I didn't notice this before...

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.

It seems that if cmake finds something like the following:

Eclipse doesn't like that and wants to have
/System/Library/Frameworks
instead

...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
is definitively newer than the other 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()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |

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.

When a search path contains multiple "lib/" instances we previously
converted all or none. This fails for cases where only some of the
multiple instances must be converted. Teach AddArchitecturePaths to
generate all combinations that exist. Uncomment these cases in the
CMakeOnly.find_library test now that they work.
Simplify cmFindLibraryCommand::AddArchitecturePaths logic to avoid
recording a separate 'found' status and populating an entire
vector<string> just to throw it away.
Previously methods AddArchitecturePaths and AddLib64Paths were almost
identical. Replace the latter with a call to the former. Fix the
AddArchitecturePaths implementation to add trailing slashes to all
tested paths.

Remove SetDefaultString and use the default component name only when an

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.

Commit 9090572f (Add ability to include a file in a project via a cache

extra "_FILE" by accident. Remove it.
In 2.8.7 running cpack with no arguments would run the packaging iff
a CPackConfig.cmake file is found whereas

This commit restore the 2.8.7.
We should add a test for this but this is not included in this commit.
This patch adds a man section number, which is then used by the
DocumentationFormatterMan. The section number is right now always 1,
detecting this from the file name will be the next step.

Since commit e1409ac5 (Support building shared libraries or modules
without soname, 2012-04-22) CMake crashes on the code
add_library(foo SHARED foo.nolang)
because the logic to lookup the language's soname flag was moved from
cmTarget::GetLibraryNames to cmMakefile::GetSONameFlag without its check
for a NULL language. Restore the check for NULL.
Add RunCMake.Languages test to cover language error cases like this one.
If a source file extension is not recognized as any language then
src.GetLanguage() may return NULL. Check the result before
dereferencing in cmLocalGenerator::GetObjectFileNameWithoutTarget.

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