Hi,
I am trying to use cmake as the building system for my project which may
use many different libraries. I only have one day experience with it
:-), so far everything works fine except that a sub-project using Qt4
can not be built. The problem is when I use INCLUDE(FindQt4), the
following errors always came out:
CMake Error: Error in cmake code at
6:39:
CONFIGURE_FILE Problem configuring file

The same problem also came out if try to build it as a stand alone
project. But if I copy a CMakeCache.txt file from a package (VTK) I
downloaded on internet to my project, then it works! Can somebody give
me some hints to solve this problem?
By the way, how can I include qt resource file *.qrc in my CMakeLists.txt?
You need to look at CMakeError.log and figure out why the try compile is
failing.

Thank you for the hint!
From the log file, I find out the problem is due to an error in
determing pthread library, it used -lpthreads flag to link the testing
code. I don't understand why it does not use -lpthread without s. I
guess this testing is invoked by the macro FIND_PACKAGE(Threads) in the
FindQt4.cmake. Is there a work around :-) for this?
