This is just OTTOMH, but could you have something like this: #include <string> const std::string link_date( __DATE__ ); const std::string link_time( __TIME__ ); in a separate blah.cc file? Then set the "blah" target to one of the PHONYs in the Makefile (those are the ones that always recompile regardless, right?), and make sure it's a requirement for every link. Not sure how else you could accomplish this. _______________________________________________ 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
