The export_library_dependencies() command should not be called.

This command was added in January 2003 to export <tgt>_LIB_DEPENDS internal CMake cache entries to a file for installation with a project. This was used at the time to allow transitive link dependencies to work for applications outside of the original build tree of a project. The functionality has been superseded by the export() and install(EXPORT) commands.

CMake >= 3.0 prefer that this command never be called. The OLD behavior for this policy is to allow the command to be called. The NEW behavior for this policy is to issue a FATAL_ERROR when the command is called.

This policy was introduced in CMake version 3.0. CMake version 3.18.20200926-gd005595 warns when the policy is not set and uses OLD behavior. Use the cmake_policy() command to set it to OLD or NEW explicitly.


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