It still not clear to me, did you delete RTK-1.3.0-build after the
install? If not, then (1) I don't understand why it does not find
librtk and (2) your LD_LIBRARY_PATH should point to
/usr/local/bin/RTK-1.3.0-build/lib

If you want to use your installed directory, you should have in Gate
RTK_DIR:PATH=/usr/local//bin/RTK-1.3.0-install/lib/cmake/RTK-1.3/
