CMP0111

New in version 3.19.

An imported target missing its location property fails during generation.

Imported Targets for library files and executables require that their location on disk is specified in a target property such as IMPORTED_LOCATION, IMPORTED_IMPLIB, or a per-configuration equivalent. If a needed location property is not set, CMake 3.18 and below generate the string <TARGET_NAME>-NOTFOUND in its place, which results in failures of the corresponding rules at build time. CMake 3.19 and above prefer instead to raise an error during generation. This policy provides compatibility for projects that have not been updated to expect the new behavior.

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 3.26.6 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.
