 * \brief      Defines SHARK_COMPILE_DLL
 * 
 * Windows requires the explicit export of symbols inside a DLL otherwise DLL symbols are not available.
 * SHARK_COMPILE_DLL is a macro that expands to nothing if SHARK_USE_DYNLIB is not defined or the compiler is not MSVC.
 * This is the case on linux systems or if no DLL is build. Otherwise, it expands to __declspec(dllexport) or __declspec(dllimport)
 * based on whether SHARK_COMPILE_DLL is defined.
