# On AIX, both shared and static libraries are archived. As a result, both the static and the shared targets end
# up with a `.a` suffix, which conflict. To workaround that, we set a different output name for the static
# libraries, which we never actually build anyway. For more information, see https://gitlab.kitware.com/cmake/cmake/-/issues/19494.
