I'm trying to compile tdesvn from 3.5.13 tarballs, but it fails on:

Apparentely it cannot find libkcal/vcaldrag.h which is present in the
system under /opt/trinity/include/kde. It's part of tdepim suite which
I have installed. Is there a quick way to fix this? Adding
/opt/trinity/include/kde to CMAKE_INCLUDE_PATH didn't help.

I noticed that many of the header files from various tde components
(but not all of them) are installed it $prefix/include/kde. Shouldn't
kde dir be replaced with trinity, or dropped? This path is present in
the main tde git tree too.
