TARGET_LINK_LIBRARIES(main /opt/foo/libf.so) would give you an RPATH in this command. But this RPATH would be patched out on make install. > Does the above-noted CMakeLists.txt actually produce different results > w.r.t. the RPATHs when using the CodeBlocksUnixMakefiles generator? Should be impossible, because the CodeBlocks generator simply generates the normal makefiles, and additionally the codeblocks xml project files.
