| # - Since we are past CMake 3.12 we can add CONFIGURE_DEPENDS to DawnGenerator to rerun CMake |
| # in case any of the generator files changes. We should also remove the CACHE "" FORCE stuff to |
| # override options in third_party dependencies. |
| # - When upgrading to CMake 3.20 we can take advantage of the GENERATED property being global in |
| # DawnGenerator. We should also use the path utilities in install_if_enabled. |
