could not find optix #23

Thanks for sharing this brilliant work! I have trouble in finding the optix module. It seems that the OptiX_INSTALL_DIR is used in FindOptiX.cmake, but this file is not in the CMAKE_MODULE_PATH. So I copy the optix/SDK/CMake/FindOptiX.cmake to instant-ngp/cmake and set OptiX_INSTALL_DIR. Now find_package can find the OptiX and OptiX_INCLUDE is set correctly, but Optix_FOUND is not set. If I manually set the Optix_FOUND, an error occurred in build optix_pth.h. How can I set optix correctly?

Well, this is mildly embarrassing. The script we are using to maintain the public version of this codebase did not copy over the cmake folder. Apologies!

I've just pushed the missing files. Please try again.

Thanks for your quick apply! Now I can build the project successfully!
