Opencv中highgui静态链接库使用时error LNK2001的错误

编译完成后的highguiDL.lib 和highguiL.lib运行时却出现以下问题，error LNK2001错误是无法找到链接库。 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIFileRelease@4 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamRelease@4 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamGetFrameClose@4 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamGetFrame@8 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamGetFrameOpen@8 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamInfoA@12 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIFileGetStream@16 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIFileOpenA@16 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIFileInit@0 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _ICClose@4 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _ICSendMessage@16 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _ICDecompress highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _ICOpen@12 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _capCreateCaptureWindowA@32 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _capGetDriverDescriptionA@20 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamSetFormat@16 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIMakeCompressedStream@16 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVISaveOptions@20 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIFileCreateStreamA@12 highguiDL.lib(cvcap_vfw.obj) : error LNK2001: unresolved external symbol _AVIStreamWrite@32 Debug/ITS_MFC.exe : fatal error LNK1120: 20 unresolved externals Error executing link.exe. 这里问题并不是opencv链接库的问题，而是opencv在调用win32下的vfw库，所以在独立工程编译的时候需要加上vfw32.lib这个系统库文件，这样才能顺利编译。
