Use CMAKE_OSX_SYSROOT and CMAKE_OSX_DEPLOYMENT_TARGET to set the Xcode
SDKROOT and MACOSX_DEPLOYMENT_TARGET build settings. This is necessary
because some versions of Xcode select a different compiler based on
these settings. We need to make sure the compiler identified during
language initialization matches what will be used for the actual build.
Initialize variables CMAKE_OSX_SYSROOT, CMAKE_OSX_DEPLOYMENT_TARGET, and
CMAKE_OSX_ARCHITECTURES prior to enabling any languages. This will
allow compiler identification to consider these values.
Create a Modules/CMakeSystemSpecificInitialize.cmake module loaded after
CMakeSystem.cmake but before per-language initialization. Use it to
load an optional Platform/<os>-Initialize.cmake module. This will be
useful to do per-platform initialization that does not depend on the
language and use the results when enabling specific languages.
In the domain clear_doc method, avoid removing entries from a dictionary
while iterating over it. Instead accumulate a set of entries to remove
at the end.
Fix cmOSXBundleGenerator::CreateCFBundle to place Info.plist under the
same root directory as the rest of the bundle. Without this, Info.plist
was placed into CMAKE_BINARY_DIR, not CMAKE_CURRENT_BINARY_DIR because
the target path was not generated correctly.
Extend CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES with these paths. We
already have the equivalents under /usr. Systems that have these
directories have their dynamic loaders configured already. Do not allow
them to appear in the RPATH explicitly.
A 64-bit MinGW windres is named "i686-w64-mingw32.shared-windres". The
get_filename_component NAME_WE mode may strip the ".shared-windres" part
and cause the result to no longer contain "windres". Instead, match the
"windres" name in the full CMAKE_RC_COMPILER value first, and use the
get_filename_component code path only for other resource compilers.
Use the CMAKE_MATCH_* variables to simplify matching logic. Match
either 3 or 4 version components. Do not fail when there are only three
components available.
QT4_CREATE_MOC_COMMAND is given a moc_flags argument that contains the
COMPILE_DEFINITIONS and a potentially large list of include directories.
Since it is a macro, the ${moc_flags} reference is replaced with this
content and sent through cmMakefile::ExpandVariablesInString (EVIS).
Since commit v3.0.0-rc1~138^2 (Qt4: Use generator expression in
COMPILE_DEFINITIONS, 2014-01-13) the COMPILE_DEFINITIONS value contains
a '$' so the EVIS fast-path is no longer used. Instead the full
cmCommandArgumentParserHelper is now used on the large input, which is
very slow (since it was originally created for hand-written code).
Change QT4_CREATE_MOC_COMMAND to a function instead of a macro to avoid
passing large content through EVIS. This makes it significantly faster.
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project. Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.
This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior. When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.
Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.
Add inline reST markup as appropriate. Word CMP0047 docs more like
those of CMP0025. State explicitly that the policies must be set
before the project or enable_language command calls.
Restore support for the undocumented <CONFIG>_LOCATION target property
removed by commit v3.0.0-rc1~175^2 (cmTarget: Remove support for
<CONFIG>_LOCATION property, 2013-12-30) as part of the CMP0026 OLD
behavior.
Override the QT_QTMAIN_LIBRARY cache variable with a regular
variable in the Qt 5 configuration. This avoids linking with the
Qt 4 version of the WinMain library.
According to the Intel release notes:
http://software.intel.com/sites/default/files/l-compiler-release-update.pdf
the __INTEL_COMPILER_UPDATE predefined macro was introduced to hold the
third version component.
