Intel oneAPI RenderKit CMake superbuild

Intel® oneAPI Rendering Toolkit CMake Superbuild

This CMake script will pull down Intel® oneAPI Rendering Toolkit libraries and build them from source. The result is an install directory with everything in it (CMAKE_INSTALL_PREFIX).

Requirements:

• A C++-14-capable compiler and libstdc++.so.6.0.21 or greater.
• CMake 3.12 or greater
• Python 3.6 or greater (including development tools) with the following packages
  • numpy
  • Note: Python 3.9 is validated for Intel® OSPRay Studio's python bindings and supported by Intel® oneAPI 2022
• Linux system requirements:
  • depending on your linux system, you may need to install X11 and GL development libraries
• For other dependencies, see latest release notes of Intel® oneAPI Rendering Toolkit components
  • https://github.com/ospray/rkcommon
  • https://github.com/embree/embree
  • https://github.com/OpenImageDenoise/oidn
  • https://github.com/openvkl/openvkl
  • https://github.com/ospray/ospray
  • https://github.com/ospray/ospray_studio
  • https://github.com/OpenPathGuidingLibrary/openpgl
  • https://github.com/ispc/ispc

Run with:

git clone https://github.com/RenderKit/superbuild
cd superbuild
mkdir build
cd build
cmake ..
cmake --build .

To validate OSPRay Studio's python bindings:

export LD_LIBRARY_PATH=<install_path>/lib
export PYTHONPATH=<install_path>/lib
python3 <build_path>/ospray_studio/source/pysg/tutorial/sgTutorial.py

By default, all projects will be installed into build/install (if following the above instructions exactly), unless CMAKE_INSTALL_PREFIX is set to somewhere else.

superbuild's Issues

CMake failure

Anyone ever see the following failure in a superbuild?

make VERBOSE=1 shows this:

[ 26%] Performing build step for 'rkcommon'
cd /home/knolla/intel/ms335/superbuild/build/rkcommon/build && cmake --build . --config release -j 32
Unknown argument -j
Unknown argument 32
Usage: cmake --build

[options] [-- [native-options]]

This is with CMake 3.19.0-rc1 (also tried 3.16, same issue), gcc 4.8.5, GNU make 3.82.

glfw and other dependencies

Is it possible/easy to automate the build of the glfw dependency?
I'd need it for a remote server where no graphic environment is installed by default ...

Thanks!
