Windows: Optionally generate DLL module definition files automatically Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically generate a module definition file from MS-compatible .obj files and give it to the linker in order to export all symbols from the .dll part of a SHARED library.

WINDOWS_EXPORT_ALL_SYMBOLS
--------------------------
This property is implemented only for MS-compatible tools on Windows.
Enable this boolean property to automatically create a module definition
(``.def``) file with all global symbols found in the input ``.obj`` files
Windows: Honor WINDOWS_EXPORT_ALL_SYMBOLS for executables with exports For executables with ENABLE_EXPORTS set, export all symbols when instructed to do so by WINDOWS_EXPORT_ALL_SYMBOLS.

for a ``SHARED`` library (or executable with :prop_tgt:`ENABLE_EXPORTS`)
on Windows. The module definition file will be passed to the linker
causing all symbols to be exported from the ``.dll``.
Windows: Optionally generate DLL module definition files automatically Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically generate a module definition file from MS-compatible .obj files and give it to the linker in order to export all symbols from the .dll part of a SHARED library.

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.
