CMAKE__LINK_DEF_FILE_FLAG ------------------------------- .. versionadded:: 4.1 Linker flag to be used to specify a ``.def`` file for dll creation with the toolchain for language ````. CMake sets this variable automatically during toolchain inspection by calls to the :command:`project` or :command:`enable_language` commands. If the :variable:`!CMAKE__LINK_DEF_FILE_FLAG` variable is defined, it takes precedence over the language-agnostic :variable:`CMAKE_LINK_DEF_FILE_FLAG` variable.
