OF not working with Visual Studio 2017

I have put the OpenFrameworks within the Visual Studio folder, and have specified the OF folder root. I have tried to launch one of the example solutions and compile and build one of the examples but I get error: MSB3073.

Please help me, I have been trying to solve this issue for a couple of days!!

which version of openFrameworks are you using?
There is no need to put the openFrameworks folder at any particular location, just dont alter its internal structure.
Open any of the examples and try to compile. There are a few files inside each example, make sure to open the file with the .sln extension.
