| CMAKE_HOME_DIRECTORY | |
| -------------------- | |
| Path to top of source tree. Same as :variable:`CMAKE_SOURCE_DIR`. | |
| This is an internal cache entry used to locate the source directory | |
| when loading a ``CMakeCache.txt`` from a build tree. It should not | |
| be used in project code. The variable :variable:`CMAKE_SOURCE_DIR` | |
| has the same value and should be preferred. |
