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.

Take our CURSES_USE_NCURSES code path when CURSES_NEED_NCURSES is
enabled even if CURSES_CURSES_LIBRARY also happens to be found.

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.
