SO basically i am trying to build Chipmunk physics library on linux mint, and it has a cmake file obviously, which i tried to run and it did not complete due to some error , the output was
cmake ..
CMake Error at CMakeLists.txt:3 (cmake_policy):
Policy "CMP0042" is not known to this version of CMake.

any idea how i can fix the cmake files to work?
Your CMake version is too old. CMP0042 was introduced in CMake 2.8.12.
You can try to remove the line in CMakeLists.txt:3, it should be make_policy(CMP0042). But no guarantee that the other parts will work as expected.
