[cmake-developers] Debugging issues with enable_language(CSHARP)

[David Cole]

Have you looked into
https://github.com/Kitware/CMake/blob/master/Modules/CMakeDetermineCSharpCompiler.cmake
?

Send steps to reproduce the problem you're seeing... Maybe somebody
else here has encountered the same thing and worked through it
already.


HTH,
David C.
