[CMake] C# Language Detection Errors in 3.8.0-rc2

[Wesley Smith]

Eventually I figured out the answer to this question after stepping through
the CMake project code.

DO:
enable_language(CSharp)

DONT:
enable_language(CSHARP)

Unlike C, CXX, FORTRAN, etc. CSharp is not an abbreviation requiring
capitalization of all letters.  Case matters.
