| <p>Prefer files from the CMake module directory when including from there.</p> |
| <p>Starting with CMake 2.8.4, if a cmake-module shipped with CMake (i.e. |
| located in the CMake module directory) calls include() or |
| find_package(), the files located in the CMake module directory are |
| preferred over the files in CMAKE_MODULE_PATH. This makes sure that |
| the modules belonging to CMake always get those files included which |
| they expect, and against which they were developed and tested. In all |
| other cases, the files found in CMAKE_MODULE_PATH still take |
| precedence over the ones in the CMake module directory. The OLD |
| behavior is to always prefer files from CMAKE_MODULE_PATH over files |
| from the CMake modules directory.</p> |
| <p>This policy was introduced in CMake version 2.8.4. CMake version |
| 3.8.2 warns when the policy is not set and uses OLD behavior. Use |
| the cmake_policy command to set it to OLD or NEW explicitly.</p> |
