I agree with you. Running valgrind directly on the cmake binary provides useful information: I can see which internal cmake functions are used the most and consume most of the time. Nevertheless, I think it would be useful to have a higher level overview. E.g. to see if there are some issues with the scripts themselves that I use in my project ... > Usually you see mostly string handling related functions. malloc and free are on the top of what I see for a random project used mostly by std::string. Maybe we can optimize something here too?
