| <p>The logical name of executable and library targets does not have to |
| correspond to the physical file names built. Consider using the |
| OUTPUT_NAME target property to create two targets with the same |
| physical name while keeping logical names distinct. Custom targets |
| must simply have globally unique names (unless one uses the global |
| property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).</p> |
| <p>This policy was introduced in CMake version 2.6.0. 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> |
