CMAKE_INCLUDE_CURRENT_DIR — CMake 4.3.0 Documentation

# CMAKE_INCLUDE_CURRENT_DIR

Automatically add the current source and build directories to the include path.

If this variable is enabled, CMake automatically adds `CMAKE_CURRENT_SOURCE_DIR` and `CMAKE_CURRENT_BINARY_DIR` to the include path for each directory. These additional include directories do not propagate down to subdirectories. This is useful mainly for out-of-source builds, where files generated into the build tree are included by files located in the source tree.

By default `CMAKE_INCLUDE_CURRENT_DIR` is `OFF`.
