One possibility is the programme might be waiting for access to some
resource. In such situations, I find strace is a livesaver. Do you have
access to that command or its equivalent for mingw?
Could you give more MinGW details? Is it bare MinGW or MinGW with
MSYS? From the CMake perspective (and probably many other perspectives),
there is a large distinction between the two.
Also, details about CMake would be useful. What version? Where did you get it?
Did you install a binary version or did you build it yourself?
