Error on non-existent target in get_target_property.
In CMake 2.8.12 and lower, the get_target_property()
command accepted
a non-existent target argument without issuing any error or warning. The
result variable is set to a -NOTFOUND
value.
The OLD
behavior for this policy is to issue no warning and set the result
variable to a -NOTFOUND
value. The NEW
behavior
for this policy is to issue a FATAL_ERROR
if the command is called with a
non-existent target.
This policy was introduced in CMake version 3.0. 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.
