The problem is, that in Windows dlls must either be in the same directory as the executable (so test-drv-info must be in this directory as well), or the PATH is set accordingly (this can't be set by cmake, since the changes of cmake to the environment variables only last as long cmake runs - so the changes are not anymore during compile time) or if the dlls are in on of the system directories (no option). > > Assuming you do come up with a build-system fix to make life easier for our > MinGW users, please think as generally as possible.

IMO the best idea is to move the test-drv-info executable in the place where the dlls are. So we get through the compiling stage without problems. The examples won't run, if the PATH wasn't set accordingly though. I think we had the same discussion before with exactly the same conclusion but nobody did the simple change :(.
