Compile OpenCV
===============

OpenCV must be build from the source files. You should create following folder
structure: **source, build_x64, install_x64**. Than open CMake and set the source
and build path. Configure the CMake file with following options:

* CMAKE_INSTALL_PREFIX: absolute path to **install_x64**.

* **BUILD** options:

.. figure:: ../images/all-in-one-create/CMake_BUILD_OPENCV.png
   :scale: 100%
   :align: center

* **WITH** options:

.. figure:: ../images/all-in-one-create/CMake_WITH_OPENCV.png
   :scale: 100%
   :align: center

* **OPENCV** options:

Check **OPENCV_GAPI_GSTREAMER** to get VideoCaptuer of OpenCV.

Start the compilation of the **INSTALL** build solution.

optional install CUDA Toolkit (e.g. 7.0, supported by OptiX as well). Is need
for Macrosim, which runs with |itom|. Delete the executable (\*.exe) from the
install_x64/x64/vc14/bin folder. They are not needed for the compilation of |itom|.

.. note::

    Check **BUILD_opencv_world** to combine all modules in one dll-file.
