​Well, I'm looking into building a tool along the lines of mock that uses
debbuild <https://secure.deepnet.cx/trac/debbuild>​ to generate Debian
packages, using hawkey to do the dependency solving for build dependencies.
The tool is going to be part of a greater system for me to have a
lightweight builder system for building DEB/RPM packages from common
sources. On the RPM side, there's mock for Fedora and I'm still trying to
work out how I'm going to do it for SUSE and Mageia. The Debian side
doesn't really have anything applicable to my needs, so I know I've got to
build it up.

​pkgconfig is only useful if the libraries are built and available on the
system. If they are not, having libhif, hawkey, librepo, *et al* using
​CMake means I can import the CMakeLists and just have it build for me
without a lot of crazy work. I've been using CMake for the vast majority of
my private projects, and all of my public projects that do require building
do use CMake. Of course, I could do custom build steps and call out to
autotools, but frankly I would prefer it if it all lived within CMake's own
world, because then the build process and targets are globally tracked.

As it is, all of libhif's dependent libraries use CMake *now*, so frankly
it makes little sense to autotoolize them when converting the libhif
buildsystem to CMake would allow the deeper integration you seek.
