Included scripts do automatic cmake_policy PUSH and POP.
|
||
|
|
|
||
|
|
In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by
|
||
|
|
the include() and find_package() commands would affect the includer.
|
||
|
|
Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were
|
||
|
|
required to isolate policy changes and protect the includer. While
|
||
|
|
some scripts intend to affect the policies of their includer, most do
|
||
|
|
not. In CMake 2.6.3 and above, include() and find_package() by
|
||
|
|
default PUSH and POP an entry on the policy stack around an included
|
||
|
|
script, but provide a NO_POLICY_SCOPE option to disable it. This
|
||
|
|
policy determines whether or not to imply NO_POLICY_SCOPE for
|
||
|
|
compatibility. The OLD behavior for this policy is to imply
|
||
|
|
NO_POLICY_SCOPE for include() and find_package() commands. The NEW
|
||
|
|
behavior for this policy is to allow the commands to do their default
|
||
|
|
cmake_policy PUSH and POP.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 2.6.3. CMake version
|
||
|
|
|release| warns when the policy is not set and uses OLD behavior. Use
|
||
|
|
the cmake_policy command to set it to OLD or NEW explicitly.
