But rather I thought that somewhere this problem was already solved, as it is not a cmake-only-problem, but a general build problem when using pkg-config on libraries which are not in default search-pathes. > In any case, the CMake documentation says that > INSTALL_RPATH_USE_LINK_PATH "...will append directories in the linker > search path and outside the project to the INSTALL_RPATH...", there > is no statement that it only applies to linker search paths that were > supplied in a certain way. That applies only to libraries, not the linker-flags which have been added behind the back of cmake's library-dependency mechanism. > [skipped] This skipped part was trying to point out a solution based on the -l and -L arguments returned by pkg-config and some cmake parsing.
