Error building the instant-ngp project

[maitreygram]

Hi. I followed your installation process from the readme. I am using windows 10. But got an error when I tried running this command

cmake . -B build

This is the error I got

-- Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.19045.
-- Targeting GPU architectures: 86
-- Module support is disabled.
-- Version: 9.0.0
-- Build type: RelWithDebInfo
-- CXX_STANDARD: 14
-- Required features: cxx_variadic_templates
-- Using Win32 for window creation
CMake Warning at CMakeLists.txt:184 (find_package):
  By not providing "FindOptiX.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OptiX", but
  CMake did not find one.

  Could not find a package configuration file provided by "OptiX" with any of
  the following names:

    OptiXConfig.cmake
    optix-config.cmake

  Add the installation prefix of "OptiX" to CMAKE_PREFIX_PATH or set
  "OptiX_DIR" to a directory containing one of the above files.  If "OptiX"
  provides a separate development package or SDK, be sure it has been
  installed.


CMake Warning at CMakeLists.txt:194 (message):
  OptiX was not found.  Neural graphics primitives will still compile and run
  correctly.  However, SDF training in 'raystab' and 'pathescape' modes will
  be significantly slower.


CMake Deprecation Warning at dependencies/pybind11/CMakeLists.txt:8 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Note that I tried building the original instant-ngp project - https://github.com/NVlabs/instant-ngp. I was able to build that without any errors. I was also able to build the original instant-ngp project from the commit you have mentioned in your readme. But I wasn't able to find these files in their build folder - ngp_shared.dll, ngp_shared.pdb

Please recommend what I can try to fix this issue. Thanks!

Hey, I'm trying to reproduce your error. Could you just provide me with some information on your machine and environment? I would be especially interested in the version of visual studio, cmake, and cuda.
