If you have an installed version of VDR on your system (i.e. there is
a vdr.pc file in /usr/share/pkgconfig) and you 'make' a plugin from
within the plugin's source directory, the information stored in that
vdr.pc file will be used.

I think what Andreas means ist, that the INCDIR of the *installed* VDR headers is currently not included in the CXXFLAGS in vdr.pc. This causes plugins to not compile for themselves even if VDR has installed (using make install) before.
