想利用QT的來做爲OPENCV的界面， 但編譯過程中遇到一些問題，編譯過程不難，只是偶爾會碰到一些奇怪的問題，一些常見的問題在百度上很容易搜索到解決方法。
在自己筆記本上編譯未發現任何問題，但在公司電腦上，cmake過程中沒有報錯，編譯卻出現了videoIO模塊怎麼都編譯不過去的現象，千辛萬苦才找到解決方法：
在opencv的源碼文件cap_dshow.cpp中添加
#define STRSAFE_NO_DEPRECATE原文鏈接：http://answers.opencv.org/question/62580/not-able-to-build-opencv3-rc1-with-debug-build-type/
我編譯的是最新的opencv3.3，在50%的時候報錯，上面的鏈接是 OpenCV3-RC1 版本，錯誤發生在43%。
錯誤信息如下：
