OpenCV_FOUND到FALSE，因此包“OpenCV”被认为是未找到 [英] OpenCV_FOUND to FALSE so package "OpenCV" is considered to be NOT FOUND
问题描述
我现在遇到问题，试图让我的cmake看到我的opencv。
我安装了opencv并且可以运行一些示例问题，并且一些给出了与我在cmake文件中获取的错误相同的错误（通过终端运行示例程序）
我试图改变环境变量路径如
http://answers.opencv.org/question/35125/cmake-linking-error-opencv_found-to-false-ubuntu/
我的bashrc文件现在看起来像
CMAKE_PREFIX_PATH = / home / durham / Desktop / OpenCV / opencv -2.4.9：$ CMAKE_PREFIX_PATH
CPATH = / home / durham / Desktop / OpenCV / opencv-2.4.9 / include：$ CPATH

PYTHONPATH = / home / durham /Desktop/OpenCV/opencv-2.4.9/lib/python2.7/dist-packages:$PYTHONPATH
，其内容/etc/ld.so.conf是
include /etc/ld.so.conf.d/*.conf include
/home/durham/Desktop/OpenCV/opencv-2.4.9
cmake文件我试图运行看起来像这样
cmake_minimum_required（VERSION 2.6）

我正在运行Ubuntu 14.04。有任何建议吗？

问题可能放在某个地方FindOpenCV.cmake文件，所以你可能试图理解它正在做什么，也许修复它 - CMake语法是相当简单。
它可能检入默认安装位置，而不是现在位置，或一些很少使用的环境变量。
I am having problems at the moment trying to get my cmake to see my opencv. I have installed opencv and can run the some of the sample problems and some give the same error as the the error I get in my cmake file (when running the sample programs through terminal)
I have tried to change the environment variable path as described in http://answers.opencv.org/question/35125/cmake-linking-error-opencv_found-to-false-ubuntu/
My bashrc file now looks like
CMAKE_PREFIX_PATH=/home/durham/Desktop/OpenCV/opencv-2.4.9:$CMAKE_PREFIX_PATH
CPATH=/home/durham/Desktop/OpenCV/opencv-2.4.9/include:$CPATH LD_LIBRARY_PATH=/home/durham/Desktop/OpenCV/opencv-2.4.9/lib:$LD_LIBRARY_PATH PATH=/home/durham/Desktop/OpenCV/opencv-2.4.9bin:$PATH
PKG_CONFIG_PATH=/home/durham/Desktop/OpenCV/opencv-2.4.9/lib/pkgconfig:$PKG_CONFIG_PATH
PYTHONPATH=/home/durham/Desktop/OpenCV/opencv-2.4.9/lib/python2.7/dist-packages:$PYTHONPATH
and the contents of /etc/ld.so.conf are
include /etc/ld.so.conf.d/*.conf include
/home/durham/Desktop/OpenCV/opencv-2.4.9
The cmake file I am trying to run looks like this
cmake_minimum_required(VERSION 2.6)

SET(CMAKE_VERBOSE_MAKEFILE TRUE) SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/config)

INSTALL(TARGETS moduleArDroneBottomCamera LIBRARY DESTINATION ${IQR_INSTALL_DIR}/iqr/lib/Modules RUNTIME DESTINATION ${IQR_INSTALL_DIR}/iqr/lib/Modules )
But when I try to generate this using the cmake gui I get the following output (cant post images yet so its in the link)

I am running Ubuntu 14.04. Any suggestions?
Thanks D
Fast and dirty solution: try to install opencv (You know, make && sudo make install). After installation header files should be inc /usr/local/include and library files should be in /usr/local/lib .
The problem might lay somewhere ind FindOpenCV.cmake file, so You might as well try to understand what it is doing and maybe fix it - CMake syntax is fairly straightforward. It might check in a default instalation location instead where it lies right now, or some rarely used environment variable.
这篇关于OpenCV_FOUND到FALSE，因此包“OpenCV”被认为是未找到的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
