OpenCV环境变量已更改

Question

我在Linux机器上独立安装了OpenCV，运行正常。我安装了ROS（随附OpenCV），今天我无法在任何OpenCV项目中运行我的CMakeLists.txt，收到错误：

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.

我确定这发生了，因为一些环境变量发生了变化，但我不知道在哪里看。

有人能引导我解决这个问题吗？

Answer 1

重新安装OpenCV解决了我的问题，因为它重新修改了环境变量。
