I am transitioning from a make based build system to cmake, overall I am quite happy with cmake, but currently there are two snags:
1) The main project I am doing this on is quite large, it produces about 300 targets. So, when I type 'make' I get 300 or so lines of "[ 27%] Built target blah..." even when there is nothing (or very little) to do. This is quite annoying. I tried messing with CMAKE_RULE_MESSAGES. I just added -DCMAKE_RULE_MESSAGES=OFF to the cmake invocation. But that didn't seem to help. 2) The follow on to this is that a 'do-nothing' build still takes about 4 seconds (or about 1.25 seconds for "make -j". The previous make based build was effectively instantaneous for a 'do-nothing' build. The do-nothing (or do very little) build is the common case so I hate to regress that far. Where should I be looking to address these issues? I suspect (2) is a result of cmake generating a recursive make system (as opposed to the current make based system we have that uses recursive includes, instead of recursive make calls). Kevin
