I also tried ccache, but it does not solve the problem, it only makes it less bad. for example: * compile branch A * switch to branch B * (possibly change some things, does not matter) * switch to branch A * compile branch A assuming we use a separate build and install dir for each branch, the second compile of branch A will take: - with timestamps check and NO ccache: 7 min - with timestamps check and ccache: 2 min - with content check and NO ccache: 5 s (assuming that content checks are much faster then compilation) _______________________________________________ CMake mailing list [email protected] http://www.cmake.org/mailman/listinfo/cmake
