From Anna Sokol, "There is no need to specify WINVER of 0x0603 in order to check for the SetProcessDPIAwareness function existence.

Browse Source 
If your current OS where the application is running is Windows 8.1 or above it the function will exist in the dll or if its below it wont.
I checked the attached code with both a Windows 7 desktop (where the function doesn't exist) and a Windows 10 tablet (where it does and had my screen scaled to 150%) and in both cases the code worked as intended."
