ldc-build-runtime requires nmake in Windows

[IGotD-]

I'm trying to build the runtime but ldc-build-runtime complains 
about nmake is missing


-- Detecting C compiler ABI info
CMake Error: Generator: execution of make failed. Make command 
was: "nmake" "/NOLOGO" "cmTC_4f748\fast"
-- Detecting C compiler ABI info - failed
-- Detecting C compile features
CMake Error: Generator: execution of make failed. Make command 
was: "nmake" "/NOLOGO" "cmTC_1d99c\fast"
-- Detecting C compile features - failed

Is it that if ldc-build-runtime is being run on a Windows machine 
it wants nmake instead of make? What If I want to run make on a 
Windows machine?
