The module definition file will be passed to the linker +causing all symbols to be exported from the ``.dll``. +For global *data* symbols, ``__declspec(dllimport)`` must still be used when +compiling against the code in the ``.dll``. All other function symbols will +be automatically exported and imported by callers. This simplifies porting +projects to Windows by reducing the need for explicit ``dllexport`` markup, +even in ``C++`` classes. + +When this property is enabled, zero or more ``.def`` files may also be +specified as source files of the target. The exports named by these files +will be merged with those detected from the object files to generate a +single module definition file to be passed to the linker. This can be +used to export symbols from a ``.dll`` that are not in any of its object +files but are added by the linker from dependencies (e.g. ``msvcrt.lib``). + +This property is initialized by the value of +the :variable:`CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS` variable if it is set +when a target is created. |
