I've installed `build-essential`, but beyond that, the build instructions in the README are pretty vague. When I run `./configure`, I get
configure: error: in `/home/dandv/prg/geany-1.36':
configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config.
This is unnecessarily painful. Ubuntu is a very popular distro. Can we please have a one-liner `apt install ...` with the deps for Ubuntu?
