Impacted areas of the software CMake on Windows with MSVC

Additional supporting information ~Not tested!~

Test results, if applicable ~Not tested!~

Update 5/12/2021: I've verified that with BUILD_SHARED_LIBS=ON, the build system (tested with NMake) cannot find the required .libs that should accompany a .dll. I've also verified that the error message in this pull request prevents the configuration when using MSVC and BUILD_SHARED_LIBS=ON. The MSVC CMake variable is True even when using all Intel compilers.

My recent recent pull request #1010 might address this issue more directly.
