Qme-ng is very hard to install on macOS

[iajoiner]

Unlike Ubuntu on which qme-ng can be installed by typing one line the program is extremely hard to install on macOS for non-computer scientists. In fact two separate libraries need to be downloaded. Moreover the official Makefile does not work.

I'm currently writing a shell script that can solve this problem. I think using my script people should be able to install qme-ng simply by double-clicking it.
