CMAKE_BINARY_DIR — CMake 3.30.1 Documentation

# 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 `CMAKE_SOURCE_DIR`.

When run in `cmake -P` script mode, CMake sets the variables `CMAKE_BINARY_DIR`, `CMAKE_SOURCE_DIR`, `CMAKE_CURRENT_BINARY_DIR` and `CMAKE_CURRENT_SOURCE_DIR` to the current working directory.
