| <p>FILE GLOB_RECURSE calls should not follow symlinks by default.</p> |
| <p>In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through |
| symlinks, sometimes coming up with unexpectedly large result sets |
| because of symlinks to top level directories that contain hundreds of |
| thousands of files.</p> |
| <p>This policy determines whether or not to follow symlinks encountered |
| during a FILE GLOB_RECURSE call. The OLD behavior for this policy is |
| to follow the symlinks. The NEW behavior for this policy is not to |
| follow the symlinks by default, but only if FOLLOW_SYMLINKS is given |
| as an additional argument to the FILE command.</p> |
| <p>This policy was introduced in CMake version 2.6.2. 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> |
