- CMP0049
- -------
- Do not expand variables in target source entries.
- CMake 2.8.12 and lower performed and extra layer of variable expansion
- when evaluating source file names:
- .. code-block:: cmake
- set(a_source foo.c)
- add_executable(foo \${a_source})
- 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.
- This policy was introduced in CMake version 3.0.
- 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.
