title: Is __declspec(dllexport) needed in cpp files
body: <p>Probably a simple question but I only have Linux to test this code on where __declspec(dllexport) is not needed. In the current code __declspec(dllexport) is in front of all files in the .h file but just in front of like 50% of the functions in the cpp file so I am wondering if they are really needed in the cpp file at all ?</p>
