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.
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 3.15.2 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.
OLD behavior of a policy is
deprecated by definition and may be removed in a future version of CMake.
