Assembler support is broken, at least for masm/64 as some user reported
here some days ago.

  enable_language(ASM_MASM)
  set(sources ${sources} X86CompilationCallback_Win64.asm)

My users say that with the previous code the build pretends to compile
the assembler file as if it were a C file.

If the other assemblers are broken too, I guess this is the reason
people are trying workarounds.
