Ok, it was a bit faster (waiting for Qt to build...)

So, please put the three attached files into the cmake Modules/ directory and 
use
ENABLE_LANGUAGE(ASM-MASM)
This should find ml64.exe .
If it doesn't, try hardcoding it for now in 
CMakeDetermineASM-MASMCompiler.cmake. 
Let me know which problems you hit.
