Well, maybe turning CMAKE_USE_PTHREADS to ON will help.   Here is what
my configuration on Debian GNU/Linux is:

//Thread library used
CMAKE_THREAD_LIBS:STRING=-lpthread

//Use the pthreads library
CMAKE_USE_PTHREADS:BOOL=ON

I think the -lpthread was auto detected.  So I'd suggest turning on
the PTHREADS bool and redoing cmake and see if it picks up pthread.

cheers,
