opencv编译:The CXX compiler identification is unknown The C compiler identification is unknown
解决方法：
Found this on Google... I would assume that in your case you would copy rc.exe and rcdll.dllto visual studio 2012vcin or wherever you have installed:
Part 2: FIX LINK : fatal error LNK1158: cannot run ‘rc.exe’
Add this toyour PATH environment variables:
C:Program Files (x86)WindowsKits8.0inx86
Copy thesefiles:
rc.exe
rcdll.dll
From
C:Program Files (x86)WindowsKits8.0inx86
To
C:Program Files (x86)MicrosoftVisual Studio 11.0VCin
Or I alsofound this:
Microsoft left a few things out of their MSVT package. Since no one knowswhether they were left out by mistake or for license reasons, no one with MSVCis too interested in giving them out. A few Google searches turn up some trickysources. Fortunately, Microsoft has finally wised up and solved this problemand many more.

A good amountof MSVT missing files are there but the missing SDK files aren't.
and this:
I had the same problem which I solved by doing this:
1. Installing the Microsoft .NetFramework 2.0
2. Adding the path of the .NET Frameworkfiles (for me "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727") toGlobal compiler settings > Programs > Additional Paths withinCode::Blocks.

Try selecting "Visual Studio 12 2013 Win64" as your generator, and your problem should be solved.
