CMake Error at CMakeLists.txt:4 (cmake_policy):
Policy CMP0053 may not be set to OLD behavior because this version of CMake
no longer supports it. The policy was introduced in CMake version 3.1.0,
and use of NEW behavior is now required.
Please either update your CMakeLists.txt files to conform to the new
behavior or use an older version of CMake that still supports the old
behavior. Run cmake --help-policy CMP0053 for more information.
