| 2 | # MACRO_OPTIONAL_ADD_SUBDIRECTORY( <dir> ) |
| 3 | # If you use MACRO_OPTIONAL_ADD_SUBDIRECTORY() instead of ADD_SUBDIRECTORY(), |
| 4 | # this will have two effects |
| 5 | # 1 - CMake will not complain if the directory doesn't exist |
| 6 | # This makes sense if you want to distribute just one of the subdirs |
| 7 | # in a source package, e.g. just one of the subdirs in kdeextragear. |
| 8 | # 2 - If the directory exists, it will offer an option to skip the |
| 9 | # subdirectory. |
| 10 | # This is useful if you want to compile only a subset of all |
| 11 | # directories. |
