CMake问题-找不到由"OpenCV"提供的软件包配置文件. [英] CMake issues -- Could not find a package configuration file provided by "OpenCV"
问题描述
我在使用Cmake构建项目时遇到了问题，这是我以前从未做过的.我是C ++和Cmake和Makefiles概念的新手.我正在尝试从GitHub上的一些代码重新创建一些结果.如果您想更详细地了解这些说明/文件，可以在这里找到:
I am having an issue building a project using Cmake, which I have never done before. I am new to C++ and the concept of Cmake and Makefiles. I am trying to recreate some results from some code off of GitHub. The instructions/files can be found here if you would like to take a more detailed look:
https://github.com/jan-dufek/Fotokite
所以基本上，他列出了四个步骤:
So basically there are four steps he lists to do:
1-)安装CMake:
1-)Install CMake:
2-)在终端中，将目录更改为项目的根目录，然后运行以下命令以生成makefile:
2-) In Terminal, change directory into the root directory of the project and run the following command to generate makefile:
cmake.
3-)编译项目:
制作
4-)运行:
./Fotokite
./Fotokite
基本上我现在停留在第二步，因为导航到该文件夹并运行"cmake"后，我在终端中始终遇到以下错误.
Basically I am stuck on the 2nd step right now because I keep getting the following error in my terminal after navigating to the folder and running "cmake .".

CMake Error at CMakeLists.txt:5 (find_package):
By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenCV", but
CMake did not find one.
Could not find a package configuration file provided by "OpenCV" with any
of the following names:
OpenCVConfig.cmake
opencv-config.cmake
Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
"OpenCV_DIR" to a directory containing one of the above files. If "OpenCV"
provides a separate development package or SDK, be sure it has been
installed.
我也将OpenCV下载到了我的桌面上，我尝试将路径合并到Cmake文件中，但是仍然没有运气.
I have OpenCV downloaded onto my Desktop as well, and I tried incorporating the path into the Cmake file but still am not having any luck.

第一次在此网站上发布，如果不清楚，抱歉，如果可以，我可以提供更多详细信息！期待您的回复.
First time posting on this website so sorry if something is unclear, if so I can provide more details! Looking forward to your responses.
推荐答案
在使用buildroot生成内容时，我也遇到了类似的问题.
I have seen similar issue while using buildroot to build something.
当我检查日志时，发现
>>> xxxxxx Configuring
>>> xxxxxx Installing to target
xxxxxxxxxxxxxx DESTDIR= xxxxxxxxxxxxxxx
请仔细查看 DESTDIR 变量.它可能会受到" FOO_INSTALL_STAGING = YES "的影响.xxx.mk文件中的命令.
please take a close look at the DESTDIR variable. it might be impacted by "FOO_INSTALL_STAGING = YES" command in xxx.mk file.
