I've been trying to get ofxFaceTracker (https://github.com/kylemcdonald/ofxFaceTracker) running for a few days now. I've installed ofxCv and the examples run correctly.
However, when I try to run the ofxFaceTracker examples, I get the following error messages:
ContourFinder.obj: error LNK2019:? Unresolved external symbol "float __cdecl ofxCv :: trackingDistance (class cv :: Rect_ const &, class cv :: Rect_ const &)" (trackingDistance @ ofxCv @@ ?

In short, its LNK2019 and LNK2001 error messages. I've done quite a bit of searching on the web concerning this issue and here's what I found.
The following websites all give the same solution to the problem, which is to replace $(IntDir) with $(IntDir)/%(RelativeDir)/ in Configuration Properties -> C/C++ -> Output File -> Object File Name.

Visual Studio 2010 & 2008 can't handle source files with identical names in different folders?
Visual Studio 2010's strange "warning LNK4042"
The problem is the C/C++ option isn't there for me. I've done more digging and found that the option only appears if you have a .cpp file in the project. The thing is, I haven't been able to add one to the project. Also, what bugs me is that according to this website (http://taka-say.hateblo.jp/entry/2016/02/24/200941 , sorry it's not in english, I used the basic Google Chrome page translator to translate it. Anyways, the images are what's important) When I do the exact same thing as the example and click on the example project in the Solution Explorer and then Properties, the only property that shows is Code Analysis. There's no C/C++ or any other option.
I'm running on Windows 8.1 64 bit, Visual Studio Community 2015, ofxFaceTracker 1.1 and the latest version of openFrameworks. I also get the projects into Visual Studio using the openFrameworks project generator.
