Does not build on either Nano or Xavier w/new VPI library

[mjshiggins]

Have tried this on both a Nano and a new Xavier. Following the readme and using the Nvidia-provided docker image, the following error occurs:

CMake Error at CMakeLists.txt:31 (find_package):
  By not providing "Findvpi.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "vpi", but
  CMake did not find one.

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

    vpiConfig.cmake
    vpi-config.cmake

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

Jetpack version on the xavier:

$ cat /etc/nv_tegra_release
# R32 (release), REVISION: 7.1, GCID: 29818004, BOARD: t186ref, EABI: aarch64, DATE: Sat Feb 19 17:07:00 UTC 202

You might be running on an older version of Jetpack than is supported by Isaac ROS. Jetpack 5.0.2 is the minimum version for the currently released Isaac ROS based on L4T 35. Jetpack 5.x does not support Jetson Nano, in fact. What platforms are you trying to run Isaac ROS on? Jetson Nano and an AGX Xavier?
