Additional requirements include:

* Relocatable packages: computing absolute paths to library files
  and include directories based on the location of the pkg file itself.
  A pkg file should know the relative paths of itself and the other
  artifacts relative to the prefix. Together this information can be
  used to construct absolute paths even after the whole prefix has
  been relocated.

* Ubiquitous availability of absolute paths from pkg files in practice.

For reference, there has been some progress in getting CMake
to export package installations as .pc files:

* install: add EXPORT mode to generate pkg-config files

However, IIRC the design work is stalled on figuring out how to map
transitive dependencies across different package representations.
