Hi. I am trying to install Yade source code, but when I run the cmake command line, I get this Error inform.

/usr/bin/cc    -o CMakeFiles/cmTC_298aa.dir/CheckSymbolExists.c.o   -c /home/mdvg/YADE/build/CMakeFiles/CMakeTmp/CheckSymbolExists.c
Linking C executable cmTC_298aa
/usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_298aa.dir/link.txt --verbose=1
/usr/bin/cc      -rdynamic CMakeFiles/cmTC_298aa.dir/CheckSymbolExists.c.o  -o cmTC_298aa 
CMakeFiles/cmTC_298aa.dir/CheckSymbolExists.c.o: In function `main':
CheckSymbolExists.c:(.text+0x1b): undefined reference to `pthread_create'
collect2: error: ld returned 1 exit status
CMakeFiles/cmTC_298aa.dir/build.make:97: recipe for target 'cmTC_298aa' failed

Makefile:126: recipe for target 'cmTC_298aa/fast' failed
make: *** [cmTC_298aa/fast] Error 2

File /home/mdvg/YADE/build/CMakeFiles/CMakeTmp/CheckSymbolExists.c:
/* */
#include <pthread.h>

int main(int argc, char** argv)
{
  (void)argv;
#ifndef pthread_create
  return ((int*)(&pthread_create))[argc];
#else
  (void)argc;
  return 0;
#endif
}

Determining if the function pthread_create exists in the pthreads failed with the following output:
Change Dir: /home/mdvg/YADE/build/CMakeFiles/CMakeTmp
