kdepim (caldav installed): fatal error: caldav.h: No such file or directory

Guys, This is probably a stupid "forest for the trees issue", but I can't get my kdepim build to find 'caldav.h'! I have caldav from quickbuilds installed: 22:21 trinity:~/tblds/trinity-kdepim> locate caldav.h /usr/include/libcaldav-0.6.2/caldav.h However, for some reason, the kdepim build isn't seeing it. I am building with: export CMAKE_PREFIX_PATH=/opt/qt:/opt/trinity export CMAKE_INCLUDE_PATH=/usr/include/libcaldav-0.6.2 cmake ${srcdir}/${_svnmod} \ -DCMAKE_INSTALL_PREFIX=${trinity_prefix} \ -DCMAKE_VERBOSE_MAKEFILE=ON \ -DQT_VERSION=3 \ -DWITH_ARTS=ON \ -DWITH_BIRTHDAYS=ON \ -DWITH_CALDAV=ON \ -DWITH_CARDDAV=ON \ -DWITH_EGROUPWARE=ON \ -DWITH_GROUPDAV=ON \ -DWITH_INDEXLIB=ON \ -DWITH_PAM=ON \ -DWITH_SASL=ON \ -DBUILD_ALL=ON make } It builds fine without: -DWITH_CALDAV=ON \ -DWITH_CARDDAV=ON \ But with the above enabled, I get the following error: [ 81%] Building CXX object kresources/caldav/CMakeFiles/kcal_caldav-shared.dir/resource.cpp.o cd /home/david/tblds/trinity-kdepim/src/build/kresources/caldav && /usr/bin/c++ -Dkcal_caldav_shared_EXPORTS -D_FILE_OFFSET_BITS=64 -DHAVE_CONFIG_H -march=i686 -mtune=generic -O2 -pipe -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -include tqt.h -fPIC -I/home/david/tblds/trinity-kdepim/src/build/kresources/caldav -I/home/david/tblds/trinity-kdepim/src/kdepim -I/home/david/tblds/trinity-kdepim/src/kdepim/libkdepim -I/opt/trinity/include -I/opt/qt/include -I/opt/qt/include/tqt -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libcaldav -o CMakeFiles/kcal_caldav-shared.dir/resource.cpp.o -c /home/david/tblds/trinity-kdepim/src/kdepim/kresources/caldav/resource.cpp In file included from /home/david/tblds/trinity-kdepim/src/kdepim/kresources/caldav/reader.h:20:0, from /home/david/tblds/trinity-kdepim/src/kdepim/kresources/caldav/resource.cpp:39: /home/david/tblds/trinity-kdepim/src/kdepim/kresources/caldav/job.h:26:24: fatal error: caldav.h: No such file or directory compilation terminated. make[2]: *** [kresources/caldav/CMakeFiles/kcal_caldav-shared.dir/resource.cpp.o] Error 1 make[2]: Leaving directory `/home/david/tblds/trinity-kdepim/src/build' make[1]: *** [kresources/caldav/CMakeFiles/kcal_caldav-shared.dir/all] Error 2 make[1]: Leaving directory `/home/david/tblds/trinity-kdepim/src/build' make: *** [all] Error 2 ==> ERROR: A failure occurred in build(). Aborting... I thought setting: export CMAKE_INCLUDE_PATH=/usr/include/libcaldav-0.6.2 would allow the build to find caldav.h, but -- it ain't working... What say the gurus? -- David C.
