Weirdly, that didn't happen on my local system, although I did see something similar when setting the PreferredToolArchitecture environment variable for the environment that CMake spawns in, but not in the global environment when running the VS IDE (CMAKE_C[XX]_COMPILER would not match the actual compiler being invoked).  Thanks for taking a look anyway!


Thank you for trying to improve the situation!
