[WIP] Try containerfile

[Timoses]

Since I always find it hell to install all build dependencies on a host machine -> Try container.

Can be built and run with:

> podman run -it --rm --ipc=host $(podman build -q -f Containerfile .)

i3-easyfocus: error while loading shared libraries: libi3ipc-glib-1.0.so.0: cannot open shared object file: No such file or directory

(alias podman=docker possible if you use Docker).

Any idea why it can't find the shared library?

This one seems to work:

Suggested change

	&& make install
	&& make prefix=/usr install

It does not seem to look for libraries inside /usr/local/lib, so the above makes it write to /usr/lib. Might alternatively work to set the LIBRARY_PATH (or similar).
