Description
MSVC64 is set by checking the value of CMAKE_CL_64 in cmake/OpenCVDetectCXXCompiler.cmake. However, there is a bug in CMake (http://www.cmake.org/Bug/view.php?id=13896) where CMAKE_CL_64 is incorrectly set to 0 for CXX projects.
Currently, the opencv project is declared in CMakeLists.txt as project(opencv CXX C), which is affected by this bug. Until CMake fixes this issue, the workaround is to change CMakeLists.txt to say project(opencv C CXX).

I can not reproduce the problem. The inserted message(STATUS "CMAKE_CL_64: ${CMAKE_CL_64}") prints "1" with VS2012 x64 and cmake 2.8.10.2.

Can you reproduce the problem as described in the cmake issue, with a fresh, trivial project?

Well, CMake confirmed (and fixed) the issue, and I've reproduced it on another machine. Can we change that line in the OpenCV CMakeLists.txt for compatibility with previous CMake versions?

The problem isn't reproduced when I specify:X:\Apps\cmake-2.8.10.2-win32-x86\bin\cmake.exe -G "Visual Studio 11 Win64" .
