| CMAKE_BINARY_DIR | |
| ---------------- | |
| The path to the top level of the build tree. | |
| This is the full path to the top level of the current CMake build | |
| tree. For an in-source build, this would be the same as | |
| :variable:`CMAKE_SOURCE_DIR`. | |
| When run in :option:`cmake -P` script mode, CMake sets the variables | |
| ``CMAKE_BINARY_DIR``, :variable:`CMAKE_SOURCE_DIR`, | |
| :variable:`CMAKE_CURRENT_BINARY_DIR` and | |
| :variable:`CMAKE_CURRENT_SOURCE_DIR` to the current working directory. |
