CMAKE_LINK_DEF_FILE_FLAG — CMake 4.3.0 Documentation

# CMAKE_LINK_DEF_FILE_FLAG

Linker flag to be used to specify a `.def` file for dll creation.

The flag will be used to add a `.def` file when creating a dll on Windows; this is only defined on Windows.

CMake sets this variable automatically during toolchain inspection by calls to the `project()` or `enable_language()` commands.

If the per-language `CMAKE_<LANG>_LINK_DEF_FILE_FLAG` variable is defined, it takes precedence over `CMAKE_LINK_DEF_FILE_FLAG`.
