-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Bastians solution seems to have fixed your problem by adding the gr-blocks library to your linker targets. But now your error exposes that you didn't link against the gr-runtime. Are you sure you have something like set(GR_REQUIRED_COMPONENTS RUNTIME BLOCKS) and not deleted the RUNTIME component, leaving only set(GR_REQUIRED_COMPONENTS BLOCKS) ?
could you please share your project (preferably on github or bitbucket or the like) or at least the CMakeLists (e.g gists.github.com, pastebin, or the like) ?
