Building MRuby in build process #2
Description
I think integrating MRuby into the build process could be useful, specially so for people that wouldn't/can't install MRuby from their software repos or for people that aren't on Linux/Unix (tho I'm not sure it could be compiled as-is even with these changes on Windows, TODO)
And anyway, in most cases projects would build their own MRuby with their own build_config.rb.
The changes required for this is specific to CMake, since its this project build system ofc. Replicating this on other build systems should be easy enough.
