刚打开会报错： error: Qt Creator needs a CMake Tool set up to build. Configure a CMake Tool in the kit options. 原因：http://doc.qt.io/qtcreator/creator-project-cmake.html 就是说你根本没往Qt中添加Cmake可执行文件的路径
1，添加cmake路径： 在命令行输入
which cmake会输出cmake的路径，添加到Qt的build and run的cmake里面 2，把这个cmake添加到kit 上面的cmake会自动添加到kit里 但是还是报错： The kit Desktop Qt 5.8.0 clang 64bit has configuration issues which might be the root cause for this problem. 如果用命令行执行cmake会提示找不到OpenCV，先解决这个问题。 参考http://www.luohanjie.com/2016-11-14/compilation-of-opencv-under-mac-counld-not-find-module-findopencv-cmake-wrong-solution.html **执行 brew ln opencv3 --force 提示 Linking /usr/local/Cellar/opencv3/3.2.0… 58 symlinks created If you need to have this software first in your PATH instead consider running: echo ‘export PATH=”/usr/local/opt/opencv3/bin:$PATH”’ >> ~/.bash_profile 也就是上面那句话创建了很多关于opencv的所以以便程序可以找到。 命令行下编译成功！**
再回到Qt下编译： 报错：No CMAKE_C_COMPILER could be found. Tell CMake where to find the compiler by setting either the environment variable “CC” or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH. 解决不了 0415更新： 在CMakeLists.txt第二行加入
SET( CMAKE_CXX_COMPILER "g++") #设定编译器 SET( CMAKE_C_COMPILER "gcc") #设定编译器就好了！！！！！！！！！！！！！！！！也就是要在PROJECT之前才可以
想用xcode直接打开cmake工程，教程：https://www.youtube.com/watch?v=-uEXVOzd364 1，下载cmake gui工具，选如下图 第一次configure好像不会让你选择generator，选择菜单栏file-delete cache然后再configure会让你选择，选择xcode，然后，configure，generate会生成xcode的工程文件，打开即可
2，选择run的参数： 选择xcode菜单栏的 然后在run里输入 /Users/kylefan/program/stitching/image/1.jpg /Users/kylefan/program/stitching/image/2.jpg /Users/kylefan/program/stitching/image/3.jpg /Users/kylefan/program/stitching/image/4.jpg /Users/kylefan/program/stitching/image/5.jpg 保存
3，选择执行stitching： 这样才能运行想要的程序。
