So I have all these third party libraries I keep a copy of... https://github.com/d3x0r/SACK/tree/master/src/contrib
So libressl for example, has cmakelists.txt https://github.com/d3x0r/SACK/blob/master/CMakeLists.txt#L680 add_subdirectory( src/contrib/libressl/${LIBRESSL_VERSION} ) which I aliased a bit for upgrade/migration/regression... I also link optionally to bullet... IF( EXISTS ${BULLET_SOURCE}/CMakeLists.txt ) # setup a bunch of options... add_subdirectory( ${BULLET_SOURCE} bullet ) In the second case, bullet is outside my source tree, (next to it with other top level projects), so I have to specify a name to be used in the CMAKE_BINARY_DIR (bullet) to use for temporary space to build... and then just link like any other included target target_link_libaraies( myThing bullet ssl tls crypto ) it's really not that hard, and if you don't understand add_subdirectory.... well... I can't imagine such a world it's so good for breaking up things into related funcational groups...
