OpenCV with Contributions for CMake

Cloning and initialization

Clone the repository in --recursive mode to fetch the submodules

git clone --recursive https://github.com/sunsided/opencv-cmake.git

If you didn't, pull the submodules using

git submodule update --init --recursive

Custom builds

Build from the build subdirectory. Note that the paths specified are considered to be examples taken from my setup. Adjust them accordingly to fit your system.

For Anaconda builds, in order to obtain the correct Python paths, this page has some nice tricks:

  • CMAKE_INSTALL_PREFIX: python3 -c "import sys; print(sys.prefix)"
  • PYTHON3_EXECUTABLE: which python3
  • PYTHON3_INCLUDE_DIR: python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())"
  • PYTHON3_PACKAGES_PATH: python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"

Ubuntu 17.04 + CUDA 8 (GTX 980 Ti)

Targeting Anaconda 4's Python 3.6. For some reason, CMake doesn't detect the include path unless the PYTHON3_INCLUDE_PATH variable (note it's _PATH, not _DIR) is set. It then also seems to expect PYTHON3_LIBRARIES (rather than PYTHON3_LIBRARY).
