[CMake] Copy file from Source to Build dir based on CMAKE_CFG_INTDIR

[Michael Jackson]

Hmm, That works great for MSVC compiles but not so great when I use ninja or makefiles (any of the single config generators). I was looking through the generator expressions on the Cmake doc site but didn't really come across anything that seems like it would get me what is needed. I guess I just put in:

If(MSVC or Xcode)
  Do this
Else()
  Do that
Endif().

Seems like this should just not be needed...

    You can use `file(GENERATE` and the `$<CONFIG>` generator expression.

For generators like “makefiles” and “ninja” this is easy and straight forward. I am having an issue getting my head wrapped around how to use CMAKE_CFG_INTDIR properly.
