20140402 cmake编译错误原因 同时装了vs2010和vs2012

1、cmake编译错误原因

在用cmake编译opencv出现的错误

The CXX compiler identification is MSVC 16.0.30319.1 

The C compiler identification is MSVC 16.0.30319.1 
Check for working CXX compiler using: Visual Studio 10 
Check for working CXX compiler using: Visual Studio 10 -- broken 
CMake Error at C:/Program Files/CMake 2.8/share/cmake-2.8/Modules/CMakeTestCXXCompiler.cmake:54 (message): 
  The C++ compiler "C:/Program Files/Microsoft Visual Studio 

  10.0/VC/bin/cl.exe" is not able to compile a simple test program.

查了很多资料，发现原来是因为我的电脑上同时装了vs2010和vs2012 vs2012自带的.NET4.5替换了原有的.NET，我卸载了vs2012以及.NET4.5组件，重新安装.NET4.0，再次Configure就好了。
