The license looks MIT-like.

Please confirm that it is at least BSD-3 compatible.

An important distinction is that `find_package` is meant for whole
packages that may contain multiple libraries and components, while
IIUC a `.pc` file is equivalent to a single CMake target.  We'll
need a way to reconcile that.  Does pkgconfig have conventions for
meta-packages that cover multiple components?

Also, how should version matching work?

Thanks,
