Generating New Schema Classes Unknown CMake command "pxr_plugin"

Community Build and Deployment

Hi everyone,

I’m currently experiencing an error in Generating New Schema Classes and haven’t been able to resolve it. Has anyone encountered a similar issue or knows what might be causing it?

Build the custom schema plugin using CMake: error

CMake Error at CMakeLists.txt:7 (include):
include could not find requested file:
pxrFunctions
CMake Error at CMakeLists.txt:10 (pxr_plugin):

Unknown CMake command “pxr_plugin”.

windows 10
cmake version 3.31.6-msvc6
OpenUSD 26.05
Python 3.10.10

For testing I used usdSchemaExamples from Open Usd

Generating New Schema Classes: Generating New Schema Classes — Universal Scene Description 26.11 documentation

step to reproduce

https://github.com/PixarAnimationStudios/OpenUSD/tree/dev/extras/usd/examples/usdSchemaExamples

copy usdSchemaExamples to a fresh working directory outside the main OpenUSD source repository:


set "USD_INSTALL_ROOT=D:/build/OpenUSD-26.05"

set "PATH=%USD_INSTALL_ROOT%/bin;%USD_INSTALL_ROOT%/lib;%PATH%"
set "PYTHONPATH=%USD_INSTALL_ROOT%/lib/python;%PYTHONPATH%"


cd /D D:\usd_builds\usd_my_schema

usdGenSchema schema.usda


# update CMakeLists.txt in my schema project directory

cmake_minimum_required(VERSION 3.14)
project(usdSchemaExamples)

find_package(pxr REQUIRED HINTS $ENV{USD_INSTALL_ROOT})

# Include USD CMake macro helpers
include(pxrFunctions)

# Build the plugin library
pxr_plugin(usdSchemaExamples

Hi @Subin , this sounds like a build configuration issue, so I’m moving your post into the “Build and Deployment” Category - hopefully someone there has an idea what may be going on.
