environment set up problem

[g-jing]

I was setting the environment as in the README.md file. However, I met an issue when installing Matterport3D simulators when executing cmake -DEGL_RENDERING=ON ..:

(envdrop) jinggu@jinggu-MS-7B79:~/Projects/R2R-EnvDrop/build$ cmake -DEGL_RENDERING=ON ..
CMake Deprecation Warning at CMakeLists.txt:2 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.


CMake Error at CMakeLists.txt:14 (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.

Do you have any idea about how to solve this issue?

Do you have OpenCV installed (and built)?
