CMP0082ΒΆ
Install rules from add_subdirectory() calls are interleaved with
those in caller.
CMake 3.13 and lower ran the install rules from add_subdirectory()
after all other install rules, even if add_subdirectory() was called
before the other install rules. CMake 3.14 and above prefer to interleave
these add_subdirectory() install rules with the others so that
they are run in the order they are declared. This policy provides
compatibility for projects that have not been updated to expect the
new behavior.
The OLD behavior for this policy is to run the install rules from
add_subdirectory() after the other install rules. The NEW
behavior for this policy is to run all install rules in the order they are
declared.
This policy was introduced in CMake version 3.14. Unlike most policies,
CMake version 3.15.7 does not warn by default when this policy
is not set and simply uses OLD behavior. See documentation of the
CMAKE_POLICY_WARNING_CMP0082
variable to control the warning.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
