Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake file has been configured and loaded during the first project() or enable_language() command. This gives the toolchain file named by CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET. This point is still early enough to set the generator toolset prior to the initialization of any languages that might use the toolset. The cmake::GeneratorToolset member variable remains an indication of what was specified by the -T option or loaded from the cache. It does not need to be updated based on the toolchain file setting. The cmMakefile::TryCompile can still pass cmake::GeneratorToolset into the inner instance because the try-compiled project will do platform and language initialization using the CMakeSystem module configured for the outer project. Extend the RunCMake.GeneratorToolset test with cases that use a toolchain file to set CMAKE_GENERATOR_TOOLSET.

-----------------------

|
* The :variable:`CMAKE_GENERATOR_TOOLSET` variable may now be
|
|
initialized in a toolchain file specified by the
|
|
:variable:`CMAKE_TOOLCHAIN_FILE` variable. This is useful
|
|
when cross-compiling with the Xcode or Visual Studio
|
|
generators.
