CMake build driver
All key properties are overridable from CLI (-p:PropName=PropVal) or PropertyGroup

CMakeProjName - project name outputted to build log
CMakeSourceDir - path to CMakeList.txt
CMakeBinaryDir - path to drop all the outputs
CMakeBuildType - any valid value of DCMAKE_BUILD_TYPE (applies to both config and build for VS)
CMakeConfigBuildType - any valid value of DCMAKE_BUILD_TYPE (for posix CLI)
CMakeVSArch - force an arch for VS generators (eg. -AWin32)
CMakeVSToolset = force an msvc platform toolset (eg. -Tv141)
CMakeGenerator - override the CMake generator
CMakeHelpLink - link to repo or other magical site when error occurs
