No, I need foo to be built before bar is inspected to gather its dependencies. And dependencies for both foo and bar are gathered when calling `cmake` to generate the Makefiles. This is how my OCaml support works at the moment. If you have suggestions for how to move the dependency generation to compile time (i.e. when calling `make`) then I'd be very glad to hear it. Or even better, be pointed to an example of how to achieve that. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
