| ------- | |
| 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. | |
