Add the missing include to fix an error when `cmake_push_check_state()`
is called and incidentally the CMakePushCheckState module is not loaded
by any other check running prior to `FindLibEdit.cmake`:
CMake Error at /var/no-tmpfs/portage/dev-util/lldb-15.0.4/work/cmake/Modules/FindLibEdit.cmake:24 (cmake_push_check_state):
