Create a Platform/Android module that includes Platform/Linux since
Android is based on Linux. Provide only the minimal settings needed to
get builds with Android NDK toolchains to work.
Disable use of RPATH since the Android loader ignores it and we cannot
predict the install destination anyway.
Android supports soname but shared library names must end in ".so" and
we cannot represent the versioned names with associated symlinks on all
host operating systems anyway. However, we do want the SONAME of
library files to be set so that linking to them by path to the library
file produces NEEDED entries with the soname and not the path. Add a
new CMAKE_PLATFORM_NO_VERSIONED_SONAME setting to tell the
cmTarget::GetLibraryNames method that not to use the VERSION or
SOVERSION target properties in the soname.
We already match lowercase 'rc'. Add 'RC' too. The latter is listed in
other CMake<LANG>Compiler modules as ignored for their languages already.

The FindQt4 module is a CMake Domain object of type "module".
Our convention for domain object document titles is "------"
and domain object document sections is "^^^^^^". Switch to
these within the FindQt4 documentation.
58f7baab FindFreetype: Indent with 2 spaces instead of 4
444f8801 FindFreetype: Use lower-case name in call to FPHSA
836a28d5 FindFreetype: Move PATH_SUFFIXES argument for more consistency
4ad6dace FindFreetype: Add newlines to reduce code width
While at it, do not cache the value since it should always be
computed directly from DOXYGEN_DOT_EXECUTABLE.

Link to it from the documentation of related properties, variables
and commands.
Extend the cmake-developer(7) documentation with notes on
extending feature support for compilers.
Add to the Platform/Windows-GNU module list of VS registry entries those
for VS 2013. Also add the name "vcvars64.bat" used by VS 10 and above
for 64-bit tools.
After finding qmake we search in QT_BINARY_DIR for the other Qt tools.
Try all versioned executable names before trying the plain executable name.
This makes it much more likely that if 2 different major versions are installed
in the same prefix CMake will be able to detect a proper set of tools.
Update cmake_minimum_required calls in CMakeLists.txt in Modules and in
CMakeLists.txt generated by other modules, so that they are always in
sync with current CMake version.
Some modules change CMake minimum required version when they are
included. For example:
cmake_minimum_required(VERSION 2.8.12)
message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
include(CheckTypeSize)
message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
will produce the following output:
2.8.12
2.6
This patch ensures that when you include a CMake module the minimum
required version and the policies set are left unchanged.
Fixes Issue #14864
Previously when linking the intermediate link file for separable compilation
the CUDA_NVCC_FLAGS* were not used. This caused tremendous confusion when
using this feature, and I consider it to be a bug. This change should fix
this.
Clang discards the entire string if it is not used, removing
the ability to read the features from the compiled binary. That
is prevented by using the symbol.
GNU with -O3 also discards the string, so use the string in a
way which is determined by a runtime value (argc) to prevent
it being discarded.
Add properties and variables corresponding to CXX equivalents.
Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.
Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.
Provide a function to write a portable header to detect compiler
features. Generate a preprocessor #error for unknown compilers
and compiler versions whose features are not yet recorded. This
error condition might be relaxed in the future, but for now it
is useful for verification of expectations.
Remove the use of check_cxx_source_compiles which is now just getting in
the way.
Blacklist the cxx_alignof feature in the test with GNU 4.7. The test
file compiles, but it is documented as available first in GNU 4.8.

Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.
This will allow sharing of the logic of the order to test compilers in
and the preprocessor macros used to do that and to determine the
version components.
Use the highest standard compile flags available if requested language
version is too new.
This supports use-cases like
set(CMAKE_CXX_STANDARD 14)
# Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
# or equivalent flag
add_executable(main main.cpp)
This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.
When ncurses is built with USE=tinfo we need to find "tinfo" as a
dependency of the main library. Otherwise 'cbreak' is missing:
ld: ...: undefined reference to symbol 'cbreak'
ld: note: 'cbreak' is defined in DSO /lib/libtinfo.so.5 so try adding
it to the linker command line
See https://bugs.gentoo.org/show_bug.cgi?id=468622 for more information.

For example if one installs Xcode 4.6 on OS X 10.9, it doesn't contain
a 10.9 SDK, so fallback to the next newest version which, in this case,
happens to be a 10.8 SDK.
This fixes bug #14572.
The MBCS (Multi-Byte Character Set) has been deprecated with VS 2013,
and MSVC no longer ships with an MBCS-version of MFC by default.
However, it can be downloaded as an add-on.
Teach InstallRequiredSystemLibraries to install the MBCS MFC only
for VS < 12 or if it happens to exist on the system.
In commit v3.0.0-rc1~103^2~3 (ExternalProject: Reattempt download when
verification fails, 2014-01-15) a reference to ${CMAKE_COMMAND} was
added to generate a reference to the CMake command in a cmake script.
Escape the '$' so that the literal variable reference appears in the
script instead of writing the path to the current cmake. This is
necessary when the path to CMake contains spaces or other characters
special to CMake syntax.

0cce556b Xcode: Use sysroot and deployment target to identify compiler
0200d0a9 OS X: Factor a Darwin-Initialize module out of Platform/Darwin
416761e3 Add platform-specific initialization step when enabling languages
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.
Old versions of aCC need a special compiler flag to get full C++98 template
support as e.g. CMake itself or the Complex and ComplexOneConfig tests need.
The same versions need a special flag to get a proper C++ library, too.
When the primary source tree path named by a DATA{} reference does not
exist, produce an AUTHOR_WARNING instead of a FATAL_ERROR. This is
useful when writing a new DATA{} reference to a test reference output
that has not been created yet. This way the developer can run the test,
manually verify the output, and then copy it into place to provide the
reference and eliminate the warning.
If the named source tree path is expected to be a file but exists as a
directory, we still need to produce a FATAL_ERROR.
Generalize the change from commit 39d0ade0 (Windows-GNU: Support
duplicate object names in large archives, 2014-04-14) to the default
archive rules. These rules have used an incremental append approach
since commit v2.8.0~1856 (Build large archives incrementally,
2008-08-04). Switch from "ar r" to "ar q" to be sure we always append
objects instead of replacing them.
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.

b735c8cb MinGW: link like on Unix and use compile flags when linking
Since commit v2.6.0~388 (Added build rule variables
CMAKE_<LANG>_ARCHIVE_..., 2008-01-29) we use separate "ar cr ..." and
"ar r ..." steps to incrementally add a large list of object files to an
archive. Since the "r" command replaces existing objects of the same
name in an archive, if multiple objects have the same file name and
appear in separate append steps then one overwrites the other. Instead,
use "ar cq ..." and "ar q ..." to always append to the archive.
We already remove the archive before creating it so this will not cause
objects to be appended to existing archives on incremental rebuilds.
The matches have already been calculated and can simply be taken from
CMAKE_MATCH_n variables. This avoids multiple compilations of the same or very
similar regular expressions.
Warn project developers at runtime that the module should not be used
anymore. Issue the diagnostic only when the project requires a new
enough CMake to use the alternative. Honor the
CMAKE_(ERROR|WARN)_DEPRECATED settings.
Update the logic added by commit 2f9ad7c6 (Fix FindMPI for the intel
compiler on linux, 2012-03-20) to use the implicit link directories for
the current ${lang} instead of hard-coding C or CXX which may not be
enabled. This is necessary for Fortran-only projects.

db924e00 CMakeRCInformation: Do not mention 'Fortran' in documentation
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.
Expect cxx_variadic_templates to implement N2555.
N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.
