As detailed in [Are Qt4 and Qt5 still supported?](https://discourse.slicer.org/t/are-qt4-and-qt5-still-supported/2233) , it is still possible to build with Qt4. That is why, @brhoom was able to build against Qt 4.8.7.

> `SetProcessDPIAware() identifier not found`

This seems to be a legitimate error, as recommended in the associated [documentation](https://msdn.microsoft.com/en-us/library/windows/desktop/ms633543%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396), we will look into switching to use `SetProcessDpiAwareness`.
