Hi everyone,
Does anyone know how to get CMake to configure properly without looking for a non-existent "pthreads" library? I'm using Qt 4.1.4 in packages on Fedora Core 5. My output reads as follows:

And the relevant section in CMakeFiles/CMakeError.log reads as follows:
Determining if the function pthread_create exists in the pthreads failed with the follow

This is the first time I've actually written a CMakeLists.txt file and tried to run it, so I'm really quite new to the game, but I wanted to build an installable source bundle for my application. Is the solution to this to suppress the attempt to use the non-existent pthreads library, and if so how? If not, does anyone know what one does?
