The opaque `CMAKE_SYSTEM_ENVIRONMENT_ID` variable is cached during the first invocation of `cmake` and is a user-defined hint about the state of the environment. When the value changes, `cmake` either does nothing, emits a warning (by default), or refreshes the cache as if by `--fresh`. The action is controlled by the `CMAKE_SYSTEM_ENVIRONMENT_ACTION` environment variable (which is not cached). Implements: #28025

Externally-defined environment identifier that is cached. The value is not
|
|
interpreted by :manual:`cmake(1)` and is a hint about the state of the
|
|
environment during the first configure. When the value changes,
|
|
:manual:`cmake(1)` by default emits a warning to the user indicating that the
|
|
environment has changed and introspection results may be out of date.
|
|
|
|
The default warning behavior can be modified by setting
|
|
:envvar:`CMAKE_SYSTEM_ENVIRONMENT_ACTION`.
