1.下载opencv 2.4.4.exe。如果只下载源代码，没有build文件夹。

2. 在环境变量中加入path\build\x86\v10\bin

3. 配置vs2010.在solution explorer-> VCC direction中：

include directories：path\build\include  path\build\include\opencv  path\build\include\opencv2

library directories：path\build\x86\vc10\lib

注意，原来的$(VCInstallDir)include ，$(VCInstallDir)atlmfc\include 和$(VCInstallDir)lib，$(VCInstallDir)atlmfc\lib，$(WindowsSdkDir)lib，$(FrameworkSDKDir)\lib要保留。不然会报错，找不到msvprtd.lib之类。

 然后在solution explorer->linker->general->additional library directories里，path\build\x86\bc10\lib

linker->debug->input里：添加依赖库（末位有d）在release->input里添加依赖库（末位无d）目录在path\build\x86\vc10\lib里。

4. 完成。
