Create platform option CMAKE_<lang>_USE_RESPONSE_FILE_FOR_INCLUDES to
enable use of response files for passing the list of include directories
to compiler command lines.
This switches the internal generation order but does not affect the
results. The new order ensures that any internal state changed by
generating target-wide flags is known when the individual rules that use
those flags are generated.
Move the GetDefineFlags call from cmLocalGenerator::GetIncludeFlags to
all call sites so that the method exclusively constructs a string of
include search path flags.
Avoid GCC warning
warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]
added by commit c6a8e4c7 (The link interface of MODULE libraries is
empty, 2011-03-09).
Several major Linux distributions still do not provide Git >= 1.6.5.0 in
their stable package lists. Prior to commit 1173cc4a (Update Git
submodules with --recursive, 2011-02-22) CTest was able to use older Git
versions but simply silently failed to update submodules recursively.
Instead of failing with older Git versions preserve the status quo and
add a warning in the update log. Users testing projects with recursive
submodules may simply update to a Git new enough to support them.
MODULE libraries cannot be linked into other libraries and executables
(just like executables without ENABLE_EXPORTS). Set the MODULE target
link interface to be empty. This allows such targets to be installed in
an EXPORT set without including all their private implementation
dependencies.
Commit afd7d4ca (Add target property LINK_SEARCH_END_STATIC, 2008-01-31)
defined a property to ensure that static runtime libraries get selected.
Add a property to specify that all libraries whose type is unknown, such
as "-lm", should be assumed static. Furthermore it assumes that an
option such as "-static" is also used so that no initial -Bstatic is
needed.

Using sort results in a possibly-modified sorting

The Clang compiler warns about extra parenthesis in the code

~ ^ ~
because the idiom is commonly used when an assignment is intended
instead of a comparison. Remove the extra enclosing layer.
Since CMake 2.6.3 add_custom_target() has a SOURCES option, this was not
yet considered in the C::B generator.
Also, now GENERATED files are not added to the project.

Now a virtual folder "Subprojects" is created, and in this virtual folder
is a linked resource for each project().
This can be considered a fix for #11657

The Intel Fortran plugin forgets to create the output directory into
which it will write a DLL's import library. Utilize the fix added by
commit f4b3bdc6 (Create an exe's implib output dir for VS, 2009-06-15)
and generalized by commit 764ac980 (Generalize exe implib dir creation
for VS, 2009-06-16). Create a pre-link rule to make the directory.
To avoid name clashes.
Before this commit, name clashes can occur when invoking gcov on a
project that uses the same file name in different directories. The
--preserve-paths flag ensures all file names have a complete path,
avoiding name clashes.
Thanks to "McBen <viertelvor12@gmx.net>" for the patch.
(Did not preserve original commit author information because
we have a push check for first and last name, and do not
accept authors with only an alias...)
Make it clear that list subcommands that modify the list
do so in the current CMake variable scope, regardless of
the original scope of the list variable involved.
RPM cannot easily 'merge' differents directory into a single RPM
with shared prefix. So more flexibility has been added to generic
CPackGenerator in order to let the specific generator chose the
local installation directory for each component.
With this commit, the --graphviz option now also generates dot files
which show which other targets depend on some target.
So, now there is
* a global dot-file which shows all targets and dependencies
* a dot file which shows on what a target Foo depends
* a dot file which shows which other targets depend on Foo
Alex
This is similar e.g. to CTEST_CUSTOM_WARNING_EXCEPTION from ctest.
GRAPHVIZ_TARGET_IGNORE_REGEX is not supported anymore.
I hope this is ok, since this was 100% undocumented and can't
break a build.
Alex
Patch from Christian Ehrlicher.
By setting GRAPHVIZ_EXTERNAL_LIBS to TRUE in CMakeGraphVizOptions.cmake
you can now exclude external libraries from the produced dot file.
I.e. then you see only the dependencies within your project.

To get rc defines to work in the VS10 IDE requires \" when
constructing PreprocessorDefinitions strings. This is different
than defines for cl.
Also, per-file rc defines were not being generated. Fix that, too.
During a try_compile cmGlobalGenerator::EnableLanguage uses results from
the outer project. Reject attempts to enable languages in the test
project that are not "ready" in the outer project. Mark a language as
"ready" when all its information has been loaded and we are ready to
generate build rules.
This also avoids infinite recursion introduced by commit 295b5b60 (Honor
CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) for projects
that set CMAKE_USER_MAKE_RULES_OVERRIDE to a file that uses try_compile.
The file is loaded along with the information for a given langauge so
the language is not yet "ready".
If CMAKE_MAKE_PROGRAM is set to devenv, then GenerateBuildCommand
uses it just like we used to do for VS8 and VS9. Otherwise, it
still uses MSBuild.
This will let us run the CMake test suite through devenv and make
sure all the solution and project files we generate are load-able
and build-able by the VS 2010 IDE, not just MSBuild.

WriteCLSources should skip source files with "obj" extensions
since WriteObjSources has already written them into the vcxproj
file. Likewise, WriteGroupSources should skip source files with
"obj" extensions to avoid receiving "item ... already exists under
the filter" project-load-time error messages from Visual Studio.
If the source-file form of try_compile is given a file name with
multiple '.' characters such as "a.b.c" use only the shortest extension
to check the language. This is the expected behavior and is consistent
with normal language extension determination in the method
cmSourceFileLocation::UpdateExtension.
Set CMAKE_RUNTIME_OUTPUT_DIRECTORY explicitly in try_compile projects so
that the COPY_FILE feature knows where to look. This makes the feature
robust against CMAKE_USER_MAKE_RULES_OVERRIDE files that set variables
like CMAKE_RUNTIME_OUTPUT_DIRECTORY or EXECUTABLE_OUTPUT_PATH.
This variable was introduced to help authors override CMake's default
platform information before any of it is cached. State this clearly in
the documentation. Explicitly discourage use for other purposes.
Previously this was used only in multi-configuration generators to
choose the configuration of try_compile and try_run at their build time.
Teach CMake to honor the variable in single-configuration generators as
the CMAKE_BUILD_TYPE.
Factor out generation of SccProjectName, SccLocalPath, and SccProvider
from cmLocalVisualStudio7Generator::WriteProjectStart and call it from
cmLocalVisualStudio7Generator::WriteProjectStartFortran too.
On Windows platforms source files may contain '\' in include directives:
#include "a\b.h"
Normalize these while scanning to use forward slashes. CMake will
convert from forward slashes to the direction preferred by the native
build tools when writing the path to 'depend.make' files.
Show "<variable|string>" explicitly in if() case documentation whenever
auto-dereferencing occurs. Reference its presence from the explanation
at the bottom.
The signature of get_test_property uses argument order
test property VAR
not
test VAR property
Also document the actual behavior when the property is not found.
Some values simply cannot be escaped properly in all contexts for all
native build tools. Document known limitations after the disclaimer
that states so.
Previously the error message for code like
add_executable(myexe does_not_exist/mysrc.c)
mentioned only that "mysrc.c" is not found. Report the directory too.
Remove the example explained by the misleading phrase "CMake will treat
it as if you wrote". This was originally added by commit a73071ca
(modified the if command to address bug 9123 some, 2009-06-12). Later
related information elsewhere in the documentation was corrected and
made precise by commit cb185d93 (Fix if() command and CMP0012 OLD/NEW
behavior, 2009-10-27) but the misleading example was not corrected.
Replace the example with a correct one that more directly covers the
case that typically surprises newcomers. Avoid recommending a "correct"
way to write code because this behavior is always specific to each case.
Also update the main documentation of the behavior to be more explicit.
Previously the Xcode generator would rerun CMake only if input file
dependencies in the top-level directory changed. Teach it to depend on
input files from all directories. Other generators already do this.

Explicitly state up front that the source-file form of the command links
an executable and expects a 'main' to be defined. While at it, update
the command signature documentation to use a syntax more consistent with
other commands. Also tweak some wording.
Teach the ArgumentExpansion test to expect flattened lists as has always
been the case in the CMake language. Now that the test should pass
enable the failure regex even when CMAKE_STRICT is not on. Replace the
reference to the old ArgumentExpansion test behavior in the workaround

13caaa3 VS10: Finish Midl support (#11461)
Although the LOCATION property is for compatibility with CMake 2.4, the
LOCATION_<CONFIG> property is modern. However, if a project reads it
and sets location-altering properties later the behavior is undefined.
See parent commit for details.
Reading the LOCATION target property currently locks down the result and
ignores any later changes to properties that affect it. This may or may
not be expected and may or may not be the behavior in earlier versions
of CMake. The property is documented as provided only for compatibility
with CMake 2.4 and alternative interfaces are now available for all
originally envisioned use cases. We want to discourage its use without
outright deprecating it. Add documentation to explicitly state that
reading the property before other properties are set is undefined.
Previously, only strings containing "http:" qualified as
URLs when found in CPACK_NSIS_MENU_LINKS. Now, we use a
regex to detect strings beginning with any of the following:
ftp://
ftps://
http://
https://
news://
mailto:
This commit also moves the caller of CreateMenuLinks outside
the "if (cpackPackageExecutables)" block, allowing clients to
use CPACK_NSIS_MENU_LINKS without also having CPACK_PACKAGE_EXECUTABLES
defined. That bit of this commit fixes the remainder of the
issue described in http://public.kitware.com/Bug/view.php?id=7828
Also, added a set(CPACK_NSIS_MENU_LINKS ...) to the CPackComponents
test to enable verifying that all of this actually works.
CMake fails to find any registry paths on Windows 2000: according to regmon
it fails with an access denied error. I double checked all the access rights
and they are fine. After checking the access modes on MSDN I found that it
says KEY_WOW64_32KEY / KEY_WOW64_64KEY are not supported on Windows 2000.
CMake does not check if the current system supports Wow64 before applying
these flags.
This commit adds a check for IsWow64Process in kernel32.dll before adding
these flags.

MUI_FINISHPAGE_RUN is frequently used with NSIS and provides a checkbox
on the finish page of an installer which specifies whether the specified
executable should be run when the installer exits. This commit adds support
for this setting in CPack.
NSIS installers default to assuming the executables exist in a
directory named "bin" under the installation directory. As this
isn't usual for Windows programs, the addition of this variable
allows the customization of this directory and links still to be
created correctly.
Previously both CPACK_NSIS_MUI_ICON and CPACK_NSIS_MUI_UNIICON
needed to be set for either to take effect. This commit allows
either to be set rather than requiring both as users may well
want to e.g. use a default uninstall icon but a custom install
icon.
This commit addresses all of the following:
http://public.kitware.com/Bug/view.php?id=8165http://public.kitware.com/Bug/view.php?id=10687http://public.kitware.com/Bug/view.php?id=11311http://public.kitware.com/Bug/view.php?id=11461
With this commit, the midl support for VS10 is as
complete as midl support ever was for VS9 and earlier.
The VSMidl test should run on all Visual Studio
generator based dashboards.
CMake no longer sends C++ compiler /D flag values
to the midl compiler in Visual Studio generated
projects. I think if we want to add that in the
future, we should add a way to pass midl compiler
specific flags and perhaps an optional way to add
in the C++ definitions, too. For now, not sending
them along gets past the immediate problem wherein
idl files in a CMake VS generated project just didn't
work at all.
The VSMidl test added in this commit was inspired by
the patch attached to 8165.
The test had to be modified such that it will run in
a directory whose name contains no spaces. There is an
existing bug filed against VS10's midl asking Microsoft
to fix that problem. But for now, the test added in this
commit works by copying the source directory to a location
that avoids spaces in the directory names.

Since commit e4beefeb (CTest: Do not munge UTF-8 output in XML files,
2009-12-08) we validate UTF-8 encoding of build and test output as it is
written to XML files. However, in cmCTestTestHandler::CleanTestOutput
we still processed test output one byte at a time and did not recognize
multi-byte UTF-8 characters. Presence of such characters caused early
truncation.
Teach CleanTestOutput to truncate test output at the limit but without
cutting it in the middle of a multi-byte encoding. Also, stop avoiding
truncation in the middle of an XML tag like "<MyElement>" because the
'<' and '>' will be properly escaped in the generated XML anyway.
This patch makes include() and find_package() prefer cmake files
located in CMAKE_ROOT over those in CMAKE_MODULE_PATH.
This makes sure that the including file gets that file included
which it expects, i.e. the one from cmake with which it was tested.
It only changes behaviour when such an included file exists both
in CMAKE_MODULE_PATH and in CMAKE_ROOT.
This comes together with a new policy CMP0017, with default
behaviour it behaves as it always did, but warns.
With NEW behaviour it includes the file from CMAKE_ROOT
instead from CMAKE_MODULE_PATH. This fixes (if CMP0017 is set)
building KDE 4.5 with cmake >= 2.8.3.
Also a basic test for this policy in included.
Check CMAKE_POLICY_DEFAULT_CMP<NNNN> for a default when policy CMP<NNNN>
would otherwise be left unset. This allows users to set policies on the
command line when the project does not set them. One may do this to
quiet warnings or test whether a project will build with new behavior
without modifying code. There may also be cases when users want to
build an existing project release using new behavior for policies
unknown to the project at the time of the release.
The header was included only under "#ifdef __linux", but not all Linux

In vs2010 a bad project file could be generated if a .c or .cxx file
was marked with HEADER_FILE_ONLY, if it was in a library that contained
both c and c++ code. This fixes the error in the code, and adds a test
for this case.
If a .sln file refers to a project file with a leading ".\", as in
".\foo.vcxproj" instead of just "foo.vcxproj" or a full path then
msbuild behaves strangely. Whenever target foo is built as a dependency
of another target, msbuild brings multiple configurations up to date
instead of just the requested configuration!
Avoid a leading ".\" in project file references to avoid this behavior.
This alternative fix to that attempted by commit 57e71533 (Avoid msbuild
idiosyncrasy that builds multiple configs, 2010-12-10) avoids use of
full path project file references which vcbuild does not support.
This reverts commit 57e71533f4.
While "msbuild" can handle full paths to project files in solutions,
the old "vcbuild" used for VS < 10 cannot. We will need another
way to fix issue #11594.
For prior versions of Visual Studio we would intentionally pass
"/nologo-" for "verbose makefiles" (CMAKE_VERBOSE_MAKEFILE ON)
when the caller did not already explicitly specify either /nologo
or /nologo-. And we still do. For the prior versions.
This had the side effect of always passing /nologo- for try_compile
operations because try_compile generates projects that have verbose
makefiles on.
However, starting with Visual Studio 10, the compiler emits
"cl ... warning D9035: option 'nologo-' has been deprecated"
when passed "/nologo-".
Therefore, this commit removes setting "/nologo-" for verbose
makefiles in the Visual Studio 10 case to avoid emitting a
warning for every single invocation of the compiler in a given
build.
With Visual Studio 10, we do not set this flag either way
and therefore, the generated project has no value for this
setting and gets Visual Studio's default value, which is
of course "/nologo", which does not produce a warning.
With Visual Studio 10, a caller can still force "/nologo-"
if desired by adding it explicitly to CMAKE_C_FLAGS or
CMAKE_CXX_FLAGS.
One of Cygwin's goals is to build projects using the POSIX API with no
Windows awareness. Many CMake-built projects have been written to test
for UNIX and WIN32 but not CYGWIN. The preferred behavior under Cygwin
in such projects is to take the UNIX path but not the WIN32 path.
Unfortunately this change is BACKWARDS INCOMPATIBLE for Cygwin-aware
CMake projects! Some projects that previously built under Cygwin and
are Cygwin-aware when they test for WIN32 may now behave differently.
Eventually these projects will need to be updated, but to help users
build them in the meantime we print a warning about the change in
behavior. Furthermore, one may set CMAKE_LEGACY_CYGWIN_WIN32 to request
old behavior during the transition.
Normally we avoid backwards incompatible changes, but we make an
exception in this case for a few reasons:
(1) This behavior is preferred by Cygwin's design goals.
(2) A warning provides a clear path forward for everyone who may see
incompatible behavior, and CMAKE_LEGACY_CYGWIN_WIN32 provides a
compatibility option. The warning and compatibility option both
disappear when the minimum required version of CMake in a project is
sufficiently new, so this issue will simply go away over time as
projects are updated to account for the change.
(3) The fixes required to update projects are fairly insignificant.
Furthermore, the Cygwin distribution has no releases itself so project
versions that predate said fixes tend to be difficult to build anyway.
(4) This change enables many CMake-built projects that did not
previously build under Cygwin to work out-of-the-box. From bug #10122:
"I have built over 120 different source packages with (my patched)
CMake, including most of KDE4, and have found that NOT defining
WIN32 on Cygwin is much more accurate." -- Yaakov Selkowitz
A fully compatible change would require patches on top of these project
releases for Cygwin even though they otherwise need not be aware of it.
(5) Yaakov has been maintaining a fork of CMake with this change for the
Cygwin Ports distribution. It works well in practice. By accepting the
change in upstream CMake we avoid confusion between the versions.
CMake itself builds without WIN32 defined on Cygwin. Simply disable
CMAKE_LEGACY_CYGWIN_WIN32 explicitly in our own CMakeLists.txt file.
Previously, we would search in the Windows registry for the path
to makensis, and fail immediately if we could not read the registry
value, assuming that it was simply not installed.
This change looks for makensis in the PATH even if the registry value
is not there, enabling the scenario where makensis is installed without
admin privileges and never even touches HKEY_LOCAL_MACHINE during the
non-admin install.
In VS9 and previous versions, :VCReportError is the goto label
to jump to after a failed custom command. It stops the build
before it tries to go any further.
In VS10, :VCEnd is the correct label to use.
Create a method in the VS generators to provide the correct
line of script to use for each version of Visual Studio.
For more internal details, search for VCEnd in the
C:\Program Files\MSBuild directory.
The KWSys SystemTools::GetMaximumFilePathLength method is poorly
conceived and should not be used. The cmDepends code honors its own
MaxPath buffer size. Just hard-code it.
The first instinct of a lot of users is to use file(GLOB) to assemble
lists of sources. Add a warning to the help text stating that it should
not be used for this purpose and briefly explain why.

A cycle exists when the DFS returns to the root node, not just when
multiple paths lead to the same node.

Evaluate in the COMMAND arguments of custom commands the generator
expression syntax introduced in commit d2e1f2b4 (Introduce "generator
expressions" to add_test, 2009-08-11). These expressions have a syntax
like $<TARGET_FILE:mytarget> and are evaluated during build system
generation. This syntax allows per-configuration target output files to
be referenced in custom command lines.
The target_link_libraries command requires its first argument to be a
target in the current directory. Document this and update the error
message to be more specific. While at it, format the error message with
a call stack.
Previously the OUTPUT arguments of add_custom_command were not
slash-normalized but those of add_library and add_executable were.
This caused the example
add_custom_command(OUTPUT a//b.c ...)
add_library(... a//b.c ...)
to fail at build time with "no rule to make a/b.c". Fix this and modify
the CustomCommand test to try it.
This method replaces '//' with '/' to make the paths look nicer.
Originally it correctly skipped a leading '//' in a UNC path as the
comment says. However, commit "Removed extra variable initializations"
(2005-04-15) accidentally removed the "pos=1" initializer. It was then
incorrectly restored by commit "Added missing variable initialization"
(2005-04-15) as just "pos=0". Restore the proper initializer.
The test for this added by commit "better coverage" (2006-07-31)
included incorrect output for a sample UNC-like path. Fix it.
Pass the full version to cmake_minimum_required(VERSION) in generated
CMake files for try_compile projects. This tells CMake not to use any
backward compatibility behavior while processing code it generates.

Remove a boolean parameter of cmGlobalGenerator::CreateGlobalTarget that

because no global targets exist before it runs anymore.
Commit e01cce28 (Allow add_dependencies() on imported targets,
2010-11-19) started using cmMakefile::FindTargetToUse to follow
dependencies, including those of GLOBAL_TARGETs like INSTALL and
PACKAGE. Since global targets exist in every directory, dependencies
between them must be traced within each directory too.
Teach FindTargetToUse to check the current directory before checking
globally. For global targets this will find the local copy. For for
normal targets this will be a no-op because they are globally unique.
This variable can be set to command line arguments which will be passed
to make when eclipse invokes make, e.g. you can enter "-j8" to get
8 parallel builds (#9930)

This authorize more control because one can set
CPACK_ARCHIVE_COMPONENT_INSTALL to ON globally
and then set it selectively to OFF inside
a CPack project config file.
Sidenote: GetOption ought to be a 'const' method.
If a .sln file refers to a project file with a leading ".\", as in
".\foo.vcxproj" instead of just "foo.vcxproj" or a full path then
msbuild behaves strangely. Whenever target foo is built as a dependency
of another target, msbuild brings multiple configurations up to date
instead of just the requested configuration!
Refer to all project files by full path to avoid this behavior.
The soname generation code was compile-time selected instead of runtime
selected. The result is that a Mac-compiled cmake used to cross-compile
Mac -> Unix generates an soname of the form libfoo.x.y.so instead of
libfoo.so.x.y as expected. Instead do a runtime check based on the
target platform.

Avoid tracing dependencies of GLOBAL_TARGET targets. The build system
generators are not designed to handle any dependencies that may be
discovered. Global targets are only generated by CMake and never have
commands that reference targets built in the project anyway.
The exception is when building CMake itself there is a special case to
use the just-built "cmake" binary in the "install" target so that CMake
can replace itself on Windows. Even in this special case we do not want
to let the "install" target depend on the "cmake" target. Doing so
breaks cases like "make -j4 install".
Commit "merge in changes for beos support" (2006-12-04) added a realpath
call for every directory parsed out of a PATH-style environment
variable. No reason was given in the commit message or comments.
The call incorrectly resolves symlinks in referenced paths. Remove it.
If BeOS support really needs it then it can be restored for that
platform with a full explanation.
The cmCustomCommandGenerator::GetCommand method completely replaces the
purpose of this method. Re-implement GetRealLocation inline at the only
remaining call site and remove it.
The Makefile, VS, and Xcode generators previously duplicated some custom
command line generation code. Factor this out into a separate class
cmCustomCommandGenerator shared by all generators.
A custom command may name a target created by add_custom_target in its
DEPENDS field. Treat this case as a target-level dependency only since
a custom target provides no standard file on which to add a file-level
dependency.
Imported targets do not themselves build, but we can follow dependencies
through them to find real targets. This allows imported targets to
depend on custom targets that provide the underlying files at build
time.
Commit 60cd72d0 (Cleaned up generation of symbolic rules, 2006-02-15)
incorrectly made these Makefile targets .PHONY even though the build
rule touches an actual file. Correct it so that the copy_f90_mod and
touch steps do not happen on every "make".
Commit 34e1ac24 (Create Fortran info variables for .mod behavior,
2010-11-12) incorrectly taught GetFortranModuleDirectory to return a
relative path. We really want to use "." as the module directory only
as a workaround for compilers that do not do so by default. Therefore
we need this default only when generating the compiler command line and
not when scanning dependencies.
Revert the previous change to GetFortranModuleDirectory and apply the
change only at one of its call sites.
Commit 3827991e (...fix...not being able to remove try compile code,
2008-03-26) introduced a loop of RemoveFile attempts to overcome
anti-virus locks on recently created try_compile executables. Fix the
logic in this loop to work when the file is already missing.
The Express Edition does not come with 64-bit tools, but one can install
the "Microsoft Windows SDK v7.1" to get them. Detect this case and
check for the SDK. If found, set PlatformToolset to use the SDK tools.
Otherwise, fail with a concise and informative error.
Commit 1a0c166 (Store direct dependencies in solutions for VS >= 8,
2010-08-20) disabled use of VS-specific global dependency analysis.
Avoid perfoming the analysis at all when it is not needed. This also
prevents creation of bogus and unused '_UTILITY' targets since they are
not needed for dependencies.
