I don't agree. ;-) The use of pkg-config is an internal detail of the
CMake modules, of which the package should have no knowledge.

On which I'll close the discussion. Thanks! :-)

If we decide so, then we should move this non-hack into the
generic-package infra, so that it benefits all packages at once, not
only cmake-based packages.
