Check this patch out: *attached*.
In there I've moved pkg-config handling into the module and made it
manually look for the .pc file (for now, only for APR). This means that
find_file will also look in Serf_ROOT as well as the other cmake specific
behaviour will be in place.
However, it has its own disadvantages and may cause several regressions:
- pkgconfig doesn't really like processing absolute paths. It works, but
they may want to maybe look in some platform specific paths which only the
pkgconfig executable may know about.
- The documentation (
https://cmake.org/cmake/help/latest/module/FindPkgConfig.html) says
that moduleSpec should be a *bare module name.* Nothing about a path.
- But our autoconf build system does rely on this behaviour already
(<svn-trunk>/build/ac-macros/serf.m4:153 → serf.m4:163). So, assuming the
cmake module doesn't do anything unusual, we should be fine.
IMHO, there is a place to experiment.
