I think cmake uses the CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES variable, which is set in UnixPaths.cmake Which of the following two modes are you using ? - explicitely specify the RPATH you want to have (wouldn't that work if it just for the libs you installed yourself, so you know the install locations ?) - let cmake automatically compute the full RPATH by enabling the target property INSTALL_RPATH_USE_LINK_PATH Alex _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
