One example seen of this so far is akonadi-4.2.61 as it fails with undefined references when it links against kdepimlibs in /usr/kde/4.2/..., here's a CMake snippet ... <snip> -- Found the KDE4 kconfig_compiler preprocessor: /usr/kde/4.3/bin/kconfig_compiler -- Found automoc4: /usr/bin/automoc4 -- Found KdepimLibs: /usr/kde/4.2/lib/KdepimLibs-4.2.0/cmake/KdepimLibsConfig.cmake </snip> There may well be other packages that compile fine but may exhibit some strange and odd bugs at runtime. I propose that we add the following line to kde4-base.eclass to ensure the correct files are compiled against. # Ensure we compile against the correct KDE-4.x files mycmakeargs="${mycmakeargs} -DCMAKE_PREFIX_PATH=${PREFIX}"
should be fixed in testing eclass, tho you wont be able to compile snapshots right now ;( blame upstream for weird naming conventions
