I wonder if getting the following output from CMake
is wrongly detected by cmake if the cpu in use is intel core i5.

General configuration for OpenCV 2.4.9 =====================================  
    Host:                        Windows 6.2 AMD64
    CMake:                       3.0.2
    CMake generator:             Visual Studio 11 2012 Win64
    CMake build tool:            C:/Windows/Microsoft.NET/Framework/v4.0.30319/MSBuild.exe
    MSVC:                        1700

As this seems to me as mistake, i highly aprechiate any enlightment on this topic.

Actually, long story short, what we call a x64 or 64 bits architecture is often called AMD64 in reference with the original design of the AMD K8 which is the first processor to have a 64bits x86 instruction set.

More info on: and especially the "Industry Naming Convention" at the end.

So, you will often encounter x64 or AMD64 in computers, depending on who is making the program mentioning it.

Thank you for the short an concise answer. Following this, i assume that the problems comming up when building opencv have nothing to do with the "AMD64".

A lot of stuff can go wrong when building OpenCV. Maybe post a question with the exact error if you have not done so yet?
