ENH: Merging CompilerId implementation from branch CMake-Modules-CompilerId to the main tree. Changes between CMake-Modules-CompilerId-bp and CMake-Modules-CompilerId-mp1 are included.

Add framework to detect compiler version with its id (#12408) Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler. Provide conversion macros DEC() and HEX() to decode decimal or hex digits from integer values. Parse the version out of the compiler id binary along with the other INFO values already present. Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format "major[.minor[.patch[.tweak]]]". Save the value persistently in CMake(C|CXX)Compiler.cmake in the build tree. Document the variable for internal use since we do not set it everywhere yet. Report the compiler version on the compiler id result line e.g. The C compiler identification is GNU 4.5.2 Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

ENH: merge CMake-CrossCompileBasic to HEAD -add a RESULT_VARIABLE to INCLUDE() -add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain -have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system) -use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to run the executables if they have a different suffix because they are probably crosscompiled, but nevertheless it should be able to find them -make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE -support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.) -move ranlib on OSX from the file command to a command in executed in cmake_install.cmake -add support for stripping during install in cmake_install.cmake -split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools -remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms -create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these -add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a list of directories which will be prepended to all search directories, right now as a cmake variable, turning it into a global cmake property may need some more work -remove cmTestTestHandler::TryExecutable(), it's unused -split cmFileCommand::HandleInstall() into slightly smaller functions Alex

ENH: Implicit link info for C, CXX, and Fortran This teaches CMake to detect implicit link information for C, C++, and Fortran compilers. We detect the implicit linker search directories and implicit linker options for UNIX-like environments using verbose output from compiler front-ends. We store results in new variables called CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES The implicit libraries can contain linker flags as well as library names.

Fix check for -isysroot on OS X Previously we checked for this flag by parsing the version number of GCC out of 'gcc --version', but this is not reliable because the format can vary greatly. Now we run 'gcc -v --help' and look for '-isysroot' in the list of options. We also now store the result on a per-language basis in the per-compiler info file "CMake<LANG>Compiler.cmake". This is necessary to make it accessible from try-compile projects so that they generate correctly.

Fix issue #10155 - default value of CMAKE_OSX_DEPLOYMENT_TARGET should always be the empty string. When the value of CMAKE_OSX_DEPLOYMENT_TARGET is the empty string, the -mmacosx-version-min flag should not show up on the compiler command line. The logic for selecting default value of CMAKE_OSX_SYSROOT is orthogonal to and independent of the value of the deployment target. The default value for CMAKE_OSX_SYSROOT is the SDK that corresponds to the current version of Mac OSX on which cmake is running.
