Add installation to install system module based on name or arbitrary path to find in system packages
Dependencies on packages which only provide files which are not pkgconfig file, C includes or binaries relative to
docbook-xsl-ns, can't be installed as system package. It's possible to provide the dependency as module built from source.
It'd be nice to be able to do so. I can do the implementation, but I'd like to make sure that this is a wanted feature.
