Current upstream version has changed the name of the library, include
paths, and CMake module names. To allow other packages to still build
using the old paths, add compat symlinks and the old CMake modules to
the -devel subpackages. These compat hacks can be removed once all
dependent packages have switched to use the new pkgconfig or CMake
files.
