project on Windows in VS but it was very-very slow and definitely cmake
generates too many project files for VS. For us it was 500+ projects in a
workspace which is too much for Visual Studio. :(

<p class=3D"">We have a rather big project and use cmake for building it. A=
t some point our cmake scripts became very slow (around 4 minutes for singl=
e cmake run). We are thinking now how to speed up it. Searching the web and=
this list didn't give any

ke's trace provides enough info for time profiling, the only thing that=
it lacks is a time stamp. Below is a small patch that adds time stamp and =
nesting level (to simplify building
a stack trace) to each trace line. Would it be possible to integrate this =
change to the main line or are there better options for time profiling of c=
