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. + +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. |
