| ------- |
| |
| Do not re-expand variables in include and link information. |
| |
| CMake 2.8.10 and lower re-evaluated values given to the |
| include_directories, link_directories, and link_libraries commands to |
| expand any leftover variable references at the end of the |
| configuration step. This was for strict compatibility with VERY early |
| CMake versions because all variable references are now normally |
| evaluated during CMake language processing. CMake 2.8.11 and higher |
| prefer to skip the extra evaluation. |
| |
| The OLD behavior for this policy is to re-evaluate the values for |
| strict compatibility. The NEW behavior for this policy is to leave |
| the values untouched. |
| |
| This policy was introduced in CMake version 2.8.11. CMake version |
| |release| warns when the policy is not set and uses OLD behavior. Use |
| the cmake_policy command to set it to OLD or NEW explicitly. |
