You’ll need to recompile Rcpp. With GNU autoconf, the normal condition is that prefix is the root of the file tree into which you install software locally, so the above command is fairly typical. This works great in conjunction. # enabled shared library, i. CMAKE_STATIC_LINKER_FLAGS:STRING= //Flags used by the linker during the creation of static libraries // during DEBUG builds. INSTALL_RPATH is a semicolon-separated list specifying the rpath to use in installed targets (for platforms that support it). Other platforms don't have this problem either by not having them (Windows) or library lookups being purely filename based (Linux and other ELF platforms) rather than supporting directory traversal like macOS does. When building a target with RPATH, CMake determines the RPATH by using the directories of all libraries to which this target links. set(CMAKE_BUILD_RPATH "/my/libs/location") specifying runtime path (RPATH) entries to add to binaries linked in the build tree (for platforms that support it).
