如何使raspicam cmake与openCV安装一起工作

Question

我很难理解如何让raspicam cmake CMakeLists.txt安装示例与我的openCV安装一起工作。

1. 首先，我安装了杰西像素SD卡。
2. 然后我用这种方式安装openCV

https://raspberrypi.stackexchange.com/questions/49668/how-do-i-install-open-cv-easily-onto-my-raspberry-pi-and-so-that-it-works

我在我命名的文件夹上安装和编译了openCV：

/home/pi/OpenCV/opencv-3.2.0/release

这里的====更新是我错过的简单解决方案，============

成功地在我的文件夹/home/pi/ OpenCV /opencv-3.2.0/release上进行本地安装之后，我还必须执行此命令，以共享默认文件夹/usr/ local /OpenCV/include /use/local/lib编译器如何具有默认路径到

$ sudo make install

然后OpenCV将安装在/usr/local/.然后raspicam默认的CMakeLists.txt cmake编译将正常工作。

============================================

然后，我从以下站点下载raspicam：

https://www.uco.es/investiga/grupos/ava/node/40我遵循编译指南，但它不知道我应该将与OpenCV文件夹相关的路径放在哪里

/home/pi/OpenCV/opencv-3.2.0/release

我把所有关于raspicam API的解压缩文件都放在带有名字的文件夹中。

/home/pi/raspicam-0.1.3

然后我做了

$ mkdir build
$ cd build
$ sudo cmake .. 

我在执行$ sudo cmake ..时收到了这个警告/错误消息

CMake Warning at CMakeLists.txt:51 (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.

我试图在/home/pi/OpenCV/opencv-3.2.0/release中的几个地方添加CMakeLists.txt，但它似乎不太合适。

Answer 1

通过在CMakeLists.txt上的第28行添加以下内容解决了问题:CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} /home/pi/opencv/OpenCV-3.2.0/release
