-# Build
-
-## Requirements
-* C++20 (at the moment)
-* OpenGL 4/OpenGL ES 3.0
-
-## Optional requirements
-* Support for OpenCL 1.2
-* Support for cl_khr_gl_sharing and cl_intel_va_api_media_sharing OpenCL extensions.
-* If you want cl-gl sharing on a recent Intel Platform (Gen8 - Gen12) you currently **need to install** [compute-runtime](https://github.com/intel/compute-runtime) from source and [my OpenCV fork](https://github.com/kallaballa/opencv) 
-
-## Dependencies
-* [OpenCV 4.x](https://github.com/opencv/opencv)
-* EGL
-* GLEW
-* GLFW3
-* [nanovg](https://github.com/inniyah/nanovg)
-* [nanogui](https://github.com/mitsuba-renderer/nanogui)
