P.s
I've tried adding the /export/msys2 directory to PATH (thought the error might be similar to the one in the previous post in this section), now get a different error:
$ make run
HOST_OS=MSYS_NT-10.0
HOST_ARCH=x86_64
checking pkg-config libraries: zlib openssl glew
[ error ] ofAppGLFWWindow: 65542: WGL: The driver does not appear to support OpenGL

My discouragement runneth over .....
