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.
