CMP0111

New in version 3.19.

An imported target with a missing location fails during generation.

Prior to this the location would be generated as <TARGET_NAME>-NOTFOUND, which would result in build failures.

The OLD behavior of this policy is to generate the location of an imported unknown, static or shared library target as <TARGET_NAME>-NOTFOUND if not set. The NEW behavior is to raise an error.

This policy was introduced in CMake version 3.19. CMake version 3.19.0-rc1 warns when the policy is not set and uses OLD behavior. Use the cmake_policy() command to set it to OLD or NEW explicitly.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
