Yes, it's only a build-time setting. It's where the linker will look for libraries that are not specified by full path. You should avoid using the link_directories command, and instead pass the full path of libraries to the target_link_libraries command. The present documentation for link_directories says "Note that this command is rarely necessary" http://cmake.org/cmake/help/v2.8.8/cmake.html#command:link_directories HTH, David > > Benjamin > > > Am 25.06.2012 um 18:15 schrieb Petr Kmoch: > >> Hi Benjamin. >> >> What you're dealing with is the runtime not finding the DLL, and cmake >> has little control over that.
