【问题描述】：
我在我的 Linux 机器上安装了独立的 OpenCV，它运行正常。我安装了 ROS（带有它的 OpenCV），今天我无法在我的任何 OpenCV 项目中运行我的 CMakeLists.txt，收到以下错误：
CMake Error at CMakeLists.txt:20 (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.
我有点确定发生这种情况是因为某些环境变量已更改，但我不知道在哪里查看。
有人能帮我看看这个吗？
【问题讨论】：
-
那么，如果您按照最后一段中的说明进行操作会怎样？
-
好吧，我重新安装了 OpenCV 并且它工作了，可能改变了环境变量。
