CMake：配置过程出错，工程文件可能无效

Question

I am new to cmake. I am trying to build opencv using cmake 3.7.2 (64 bit)to be used in Qt. I am working on a windows 10 64 bit system. I have followed the steps given in the link: https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows

As per the instructions I installed Qt-Qt5.9-MingGW 5.3.0 32 bit.

The path for MinGW is also set to C:\Qt\Tools\mingw530_32\bin.

The link above shows the following instructions:

Compiling OpenCV

When I followed the instructions for building opencv I got the following error after clicking "Configure"

Error message

It would be good if someone can help me with this problem.

Answer 1

I believe you missed the instruction to set QT_MAKE_EXECUTABLE and other variables in cmake-gui. The instructions from the https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows documentation state this:

Set QT_MAKE_EXECUTABLE to D:\Qt\5.9\mingw53_32\bin\qmake.exe Set Qt5Concurrent_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Concurrent Set Qt5Core_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Core Set Qt5Gui_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Gui Set Qt5Test_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Test Set Qt5Widgets_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5Widgets Set Qt5OpenGL_DIR to D:\Qt\5.9\mingw53_32\lib\cmake\Qt5OpenGL Set CMAKE_BUILD_TYPE to Release or RelWithDebInfo Set OPENCV_VS_VERSIONINFO_SKIP=1

You do these inside cmake-gui
