    CMake: Add -T option to choose a generator toolset · 4fd53429
    Brad King authored
    Reject the option by default.  It will be implemented on a per-generator
    basis.  Pass the setting into try_compile project generation.  Add cache
    entry CMAKE_GENERATOR_TOOLSET and associated variable documentation to
    hold the value persistently.
    
    Add a RunCMake.GeneratorToolset test to cover basic "-T" option cases.
    Verify that CMAKE_GENERATOR_TOOLSET is empty without -T, that -T is
    rejected when the generator doesn't support it, and that two -T options
    are always rejected.
