cmake-2.6.2-r1 was installed; I wanted to install kdeplasma-addons-4.2.1-r1 (which did not require a newer cmake) Extract from paludis output: ... >>> Starting src_configure >>> Working in BUILD_DIR: "/var/tmp/paludis/kde-base-kdeplasma-addons-4.2.1-r1/work/kdeplasma-addons_build" loading initial cache file /var/tmp/paludis/kde-base-kdeplasma-addons-4.2.1-r1/temp//gentoo_common_config.cmake -- The C compiler identification is GNU -- The CXX compiler identification is GNU -- Check for working C compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc -- Check for working C compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-g++ -- Check for working CXX compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-g++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Looking for Q_WS_X11 -- Looking for Q_WS_X11 - found -- Looking for Q_WS_WIN -- Looking for Q_WS_WIN - not found. -- Looking for Q_WS_QWS -- Looking for Q_WS_QWS - not found. -- Looking for Q_WS_MAC -- Looking for Q_WS_MAC - not found. -- Found Qt-Version 4.4.2 (using /usr/bin/qmake) -- Looking for XOpenDisplay in /usr/lib64/libX11.so;/usr/lib64/libXext.so;/usr/lib64/libXft.so;/usr/lib64/libXau.so;/usr/lib64/libXdmcp.so;/usr/lib64/libXpm.so -- Looking for XOpenDisplay in /usr/lib64/libX11.so;/usr/lib64/libXext.so;/usr/lib64/libXft.so;/usr/lib64/libXau.so;/usr/lib64/libXdmcp.so;/usr/lib64/libXpm.so - found -- Looking for gethostbyname -- Looking for gethostbyname - found -- Looking for connect -- Looking for connect - found -- Looking for remove -- Looking for remove - found -- Looking for shmat -- Looking for shmat - found -- Looking for IceConnectionNumber in ICE -- Looking for IceConnectionNumber in ICE - found -- Found X11: /usr/lib64/libX11.so -- Looking for include files CMAKE_HAVE_PTHREAD_H -- Looking for include files CMAKE_HAVE_PTHREAD_H - found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE -- Found Automoc4: /usr/bin/automoc4 -- Found Perl: /usr/bin/perl -- Performing Test _OFFT_IS_64BIT -- Performing Test _OFFT_IS_64BIT - Success -- Performing Test HAVE_FPIE_SUPPORT -- Performing Test HAVE_FPIE_SUPPORT - Success -- Performing Test __KDE_HAVE_W_OVERLOADED_VIRTUAL -- Performing Test __KDE_HAVE_W_OVERLOADED_VIRTUAL - Success -- Phonon Version: 4.3.0 -- Found Phonon: /usr/lib64/libphonon.so -- Found Phonon Includes: /usr/include/KDE;/usr/include -- Found KDE 4.2 include dir: /usr/kde/4.2/include -- Found KDE 4.2 library dir: /usr/kde/4.2/lib64 -- Found the KDE4 kconfig_compiler preprocessor: /usr/kde/4.2/bin/kconfig_compiler -- Found automoc4: /usr/bin/automoc4 CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:57 (MESSAGE): Could NOT find KDE4Workspace (missing: KDE4Workspace_CONFIG) Call Stack (most recent call first): /usr/kde/4.2/share/apps/cmake/modules/FindKDE4Workspace.cmake:70 (find_package_handle_standard_args) CMakeLists.txt:9 (find_package) -- Configuring incomplete, errors occurred! !!!

can't reproduce with 4.2.3 and cmake-2.6.2-r1 please double check
This error is most certainly caused by the fact, that KDE workspace libs and kdeplasma-addons have been built with *different* cmake versions - workspace libs presumably with >=2.6.3 (placing exports in <libdir>/cmake/<export>) and kdeplasma-addons with 2.6.2 (placing exports and looking for them in <libdir>/<export>/cmake/).
so as a 'solution' - reemerge libkworkspace and kdeplasma-addons using the same cmake
