qt creator opencv windows cmake錯誤

Question

我想為qt creator配置然后生成opencv庫以鏈接它們。 我打開了cmake 3.1.0並輸入了源代碼和構建路徑。

資源：

C:/Users/Philipp_Laptop/Downloads/opencv/sources
build: C:/opencv-mingw

---

然后我用路徑配置了mingw-compiler：

C:/Qt/Tools/mingw482_32/bin/gcc.exe
C:/Qt/Tools/mingw482_32/bin/g++.exe

---

配置成功后，我設置了with_Qt選項。 我配置了兩次，它顯示以下錯誤：

Answer 1

我在Windows下使用了CMake GUI ，所以我將參考這種方法。 讓我們從與CMAKE_PREFIX_PATH not defined相關的問題開始。 要解決此問題，您只需在CMAKE GUI上按ADD並添加名為CMAKE_PREFIX_PATH PATH類型的變量，其值為C:/Bin/Qt/5.3/mingw482_32/lib/cmake/但使用您自己的Qt5安裝。 您現在指向的目錄包含您需要的所有模塊：Qt5目錄，Qt5AxBase ...

此時按下configure，您應該使QT_QMAKE_EXECUTABLE無效。 在我的情況下你需要正確設置它： C:/Bin/Qt/5.3/mingw482_32/bin/qmake.exe 。

然后再次按配置，看看是否仍然存在一些錯誤（你有其他錯誤，我從未見過，但也許它們是以前的錯誤），在我的情況下，這解決了所有問題並且構建繼續進行。

MINGW配置似乎沒問題：我只是將bin MINGW路徑作為第一個條目放在PAT變量中並使用CMAKE中的默認編譯器（但您的解決方案與我的解決方案一樣有效）。
