我想配置，然后生成opencv库qt creator链接他们。 我打开cmake 3.1.0并输入源代码和构建路径。

源：

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

然后我使用以下路径配置mingw编译器：

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

配置成功后，设置with_Qt选项。 我配置了两次，它显示以下错误：

解决方案

我在Windows下使用 CMake GUI ，所以我会参考这个方法。 让我们从与 CMAKE_PREFIX_PATH未定义相关的问题开始。 要解决这个问题，您只需在 CMAKE GUI 上按 ADD ，并添加名为 CMAKE_PREFIX_PATH $ c>与值 C：/Bin/Qt/5.3/mingw482_32/lib/cmake / ，但使用您自己的安装 Qt5 。现在你指定的目录包含你需要的所有模块：Qt5目录，Qt5AxBase ...

此时你按配置，你应该有 QT_QMAKE_EXECUTABLE 无效。您需要正确设置，在我的情况下： 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错误（你有其他错误，我从来没有看到，但也许他们是以前的结果），在我的情况下，这解决了所有问题，并继续构建。 / p>

配置看起来不错：我将PING变量中的bin MINGW路径作为第一个条目并使用默认编译器来自 CMAKE （但您的解决方案与我的一样有效）。

I want to configure and then generate opencv library for qt creator to link them. I opened cmake 3.1.0 and typed in the source and build path.

source:

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

Then I configured the mingw-compiler with the path:

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

After successful configure i set the with_Qt option. I configured it twice and it shows me the following error:

解决方案

I used CMake GUI under Windows for this so I'll refer to this approach. Let's start from problems related to CMAKE_PREFIX_PATH not defined. To solve this you simply have to press ADD on the CMAKE GUI and add the variable of type PATH named CMAKE_PREFIX_PATH with value C:/Bin/Qt/5.3/mingw482_32/lib/cmake/ but using your own installation of Qt5. The directory you point now contains all modules you need: Qt5 directory, Qt5AxBase...

At this point you press configure and you should have QT_QMAKE_EXECUTABLE not valid. You need to set it properly, in my case: C:/Bin/Qt/5.3/mingw482_32/bin/qmake.exe.

Then press configuration again and see if some error is still present (you have others error I never saw but maybe they are consequence of the previous ones), in my case this solved all issues and the build proceeded.

The MINGW configuration seems to be fine: I did slightly different just putting the bin MINGW path in PAT variable as first entry and using the default compiler from CMAKE (but your solution is as valid as my one).
