Cant run demo plugins from projucer

I downloaded the 4.3.0 update and decided to try out the demos in the examples folder before getting started. AnnimationAppExample compiles and runs fine but when I tried the plugins in the PluginSamples folder I’m getting all kinds of errors saying "error c1083:cannot open source file(lists 20 different cpp files here):no such file or directory. I’m sure it’s something simple but I’m new with JUCE and cannot figure it out.

I’m on Windows 10 using Visual Studio 2013. Any help is appreciated.
