Support building with Ninja using MSVC

When compiling using MSVC and Ninja the compiler flags are not correctly set cause the tool fails to identify the compiler.
This can be avoided by extending the identification mechanism for compiler in SetCompilerOptions.cmake, e.g. also checking for MSVC compiler ID.

Start in SetCompilerOptions.cmake and inspect how compiler identification and flags are selected for MSVC with the Ninja generator. Reproduce or inspect the MSVC/Ninja configuration, then verify that the compiler is identified correctly and the appropriate flags are set when building with that combination.
