[CMake] Problem embedding Python in C

[Ángel Alonso]

Hi,

I'm using cmake for a project that embed Python in  C.

For include the Python libs i use: include(FindPythonLibs)

But compiling, I get this errors:

/usr/lib/python2.6/config/libpython2.6.a(posixmodule.o): In function 
`posix_tmpnam':

I also try include(FindThreads) but the problem persist.

I think that is a problem of cmake, because in other tests that I made 
(with a simple Makefile, not cmake) it works.

Cheers
