Support WINDOWS_EXPORT_ALL_SYMBOLS with `.def` files
The WINDOWS_EXPORT_ALL_SYMBOLS
target property exports all symbols found in object files explicitly given to the linker. However, the linker may also find additional symbols in dependencies and copy them into the linked binary (e.g. from msvcrt.lib
). Provide a way to export an explicit list of such symbols by adding a .def
file as a source file.
