| Do not expand variables in target source entries. |
| |
| CMake 2.8.12 and lower performed an extra layer of variable expansion |
| when evaluating source file names:: |
| |
| set(a_source foo.c) |
| add_executable(foo \${a_source}) |
| |
| .. note: no cmake highlighting since this syntax is deprecated |
| |
| This was undocumented behavior. |
| |
| The ``OLD`` behavior for this policy is to expand such variables when processing |
| the target sources. The ``NEW`` behavior for this policy is to issue an error |
| if such variables need to be expanded. |
