Strict checking for the
CMake 3.1 and lower allowed calls to the
break() command outside of a loop context and also ignored any given arguments. This was undefined behavior.
OLD behavior for this policy is to allow
break() to be placed outside of loop contexts and ignores any arguments. The
NEW behavior for this policy is to issue an error if a misplaced break or any arguments are found.
This policy was introduced in CMake version 3.2. CMake version 3.15.2 warns when the policy is not set and uses
OLD behavior. Use the
cmake_policy() command to set it to
OLD behavior of a policy is
deprecated by definition and may be removed in a future version of CMake.
