I'm continuing to experiment with trying to build Python bindings for
KF5. As part of that, the SIP tooling creates C++ wrapper code which
must be compiled for each framework, and for that I need to know the
header file directories. So far, I have simply been hardcoding the
needed paths on my own system, but I now want to move to using
standard CMake-based logic instead.

(In some sense, this might be seen as similar to the stuff that was
added to ECM, but I'm trying for a significantly more automated

Also, I am trying to feel my way towards a Pythonic build system for
the KF5 bindings (as, roughly speaking, PyQt seems to be doing): in
other words I'm interested in using CMake as a stepping stone, not the
actual build system.

Thus, I'm after the moral equivalents of:


Thanks, Shaheed
