This one: http://sourceware.org/pthreads-win32/ ? 3 years ago I was using it (to make that software easily portable). I also think FindThreads.cmake is somewhat strange, doesn't it basically load the thread library of the current platform ? That means that you get different APIs on different platforms and therefor need different code ?
