| 8 | # This CMake module finds the Meta include directory. This module sets the | |
| 9 | # following CMake variables: | |
| 10 | # | |
| 11 | # Meta_FOUND | |
| 12 | # Set to 1 when the Meta include directory is found, 0 otherwise. | |
| 13 | # | |
| 14 | # Meta_INCLUDE_DIR | |
| 15 | # If the Meta include directory is found, this is set to the path of that | |
| 16 | # directory. Otherwise, this is not set. | |
| 17 | # | |
| 18 | # | |
| 19 | # The following variables can be used to customize the behavior of the module: | |
| 20 | # | |
| 21 | # Meta_INCLUDE_DIR | |
| 22 | # The path to the Meta include directory. When set, this will be used as-is. | |
| 23 | # | |
| 24 | # Meta_CLONE_IF_MISSING | |
| 25 | # If the Meta include directory can't be found and this is set to true, | |
| 26 | # the Meta project will be cloned locally. | |
