RESOURCE_LOCK — CMake 3.27.7 Documentation

# RESOURCE_LOCK

Specify a list of resources that are locked by this test.

If multiple tests specify the same resource lock, they are guaranteed not to run concurrently.

See also `FIXTURES_REQUIRED` if the resource requires any setup or cleanup steps.

Both the `RESOURCE_GROUPS` and `RESOURCE_LOCK` properties serve similar purposes, but they are distinct and orthogonal. Resources specified by `RESOURCE_GROUPS` do not affect `RESOURCE_LOCK`, and vice versa. Whereas `RESOURCE_LOCK` is a simpler property that is used for locking one global resource, `RESOURCE_GROUPS` is a more advanced property that allows multiple tests to simultaneously use multiple resources of the same type, specifying their requirements in a fine-grained manner.
