Utility targets may not have link dependencies.
CMake 2.8.12 and lower allowed using utility targets in the left hand side
position of the target_link_libraries()
command. This is an indicator
of a bug in user code.
The OLD
behavior for this policy is to ignore attempts to set the link
libraries of utility targets. The NEW
behavior for this policy is to
report an error if an attempt is made to set the link libraries of a
utility target.
This policy was introduced in CMake version 3.0. CMake version
3.25.3 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.
