OpenCV生成文件不会生成可执行文件

Question

我是C ++的新手，我正在尝试使用Cmake https://docs.opencv.org/master/db/df5/tutorial_linux_gcc_cmake.html

重新创建openCV教程。

我下载了Windows的.exe，并通过

用cmake构建了源代码。

cmake.exe -G "MinGW Makefiles"

然后，我尝试在带有调试标志的项目文件夹中使用make命令。我收到以下输出：

我不太了解输出，因此谷歌搜索并没有帮助。由于我最后没有可执行文件（如本教程中所述），因此似乎存在一些问题。我想念什么？

CMakeLists.txt：

cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
set(OpenCV_DIR "C:/Users/XXX/opencv/opencv")
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )

CMake输出：

cmake.exe -G "MinGW Makefiles"
CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.
