New in version 3.17.
target_compile_options() now honors BEFORE keyword in all scopes.
In CMake 3.16 and below the target_compile_options() ignores the
BEFORE keyword in private scope. CMake 3.17 and later honors
BEFORE keyword in all scopes. This policy provides compatibility for
projects that have not been updated to expect the new behavior.
The OLD behavior for this policy is to not honor BEFORE keyword in
private scope. The NEW behavior of this policy is to honor
BEFORE keyword in all scopes.
This policy was introduced in CMake version 3.17. Use the
cmake_policy() command to set it to OLD or NEW explicitly.
Unlike many policies, CMake version 3.24.4 does not warn
when this policy is not set and simply uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
