Perhaps you've had a project where you wanted to simply build Portmidi for linux, just like I did.
Maybe you wanted a docker container that needed portmidi, perhaps a small container, but noticed that
the busybox-gcc containers didn't seem to have cmake in their package-manager target list,
which, unfortunately, portmidi officially depends on to build.
So, being crazy, you decide to bypass cmake and make a simple Makefile build of portmidi using clues
derived from what cmake actually does via the compiler by putting cmake into verbose-output mode.
Well, maybe this helps you, or maybe I'm the only fool needing this.
Either way, using this is simple:
make clean
make
sudo make install
By default, the portmidi library will end up in /usr/local/lib, and the headers in /usr/local/include.
You can change this by editing PREFIX in the Makefile.
