Currently we use

fs.execute_string(rockspec.variables.CMAKE.." . " ..args
fs.execute_string(rockspec.variables.MAKE.." -fMakefile")
fs.execute_string(rockspec.variables.MAKE.." -fMakefile install")

Which use make to build the module.

But cmake have more portable way to build project:

cmake -Bbuild -H.
cmake --build build --target install --config Release

This will let cmake to choose best generator and build it in a portable way.

This solution have follow advantages:

1. One command to build all platform (with cmake installed).
2. Better for windows, we don't need to run under MSVC command prompt
