Hi Michael, In you simple example adding SET(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib") before ADD_LIBRARY(...) does trigger a re-build of the library when changing the length of CMAKE_INSTALL_PREFIX. The reason for this behavior was given by Alex Neundorf: > Then you set the install RPATH once to "/build/mato/ROOT/install/lib" and > then > to "/build/mato/ROOT/install2/lib", which is one byte longer. So the binary > has to be created again with one byte more room for the install RPATH. The fact that the build is re-done because I change the length of the installation destination I would call this a bug and not really a feature. ------------------------------------------------------------- Pere Mato CERN, PH Department, CH 1211 Geneva 23, Switzerland e-mail: pere.m...@cern.ch tel: +41 22 76 78696 fax: +41 22 76 68792 gsm: +41 76 48 70855 _______________________________________________ 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
