I want install open cv and when step using cmake I get stucked.

here the error

CMake Error at CMakeLists.txt:9 (find_package):
  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core" with any
  of the following names:




Qt5CoreConfig.cmake

qt5core-config.cmake

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
  "Qt5Core_DIR" to a directory containing one of the above files.  If
  "Qt5Core" provides a separate development package or SDK, be sure it has
  been installed.

  • Is there any important reason why you try to install OpenCV from sources by compiling it? – Ingo Sep 15 at 9:49
  • Did you try to do what the error message tells you to do? – Dmitry Grigoryev Sep 15 at 10:06
