CMAKE_CONFIG_DIR — CMake 3.31.3 Documentation

# CMAKE_CONFIG_DIR

Added in version 3.31.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

Specify a CMake user-wide configuration directory for `cmake-file-api(7)` queries.

If this environment variable is not set, the default user-wide configuration directory is platform-specific:

- Windows: `%LOCALAPPDATA%\CMake`

- macOS: `$XDG_CONFIG_HOME/CMake` if set, otherwise `$HOME/Library/Application Support/CMake`

- Linux/Other: `$XDG_CONFIG_HOME/cmake` if set, otherwise `$HOME/.config/cmake`
