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

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?

You can use Ninja with `--ninja` in the ldc-build-runtime, though GNU make should work too. See https://wiki.dlang.org/Building_LDC_runtime_libraries.

Are there any parameters that can set make instead of nmake. In practice ldc-build-runtime uses CMake and there should be a switch should be added so that you can choose any generator system you want. Bascially the -G switch in CMake.

You can set arbitrary CMake variables, but no extra cmdline options. It uses the default CMake generator without `--ninja`, so I guess it depends on your PATH and whatever it finds in there in some order. If you need advanced CMake functionality, just execute it yourself (encouraged anyway if you plan to work on druntime and rebuilding countless times), the few cmdlines automated by ldc-build-runtime are printed out. Or submit a patch for the little tool if you really want to see the feature in there. There are or have been concurrency issues with GNU make though, so I'd recommend Ninja anyway.
