# Dirty compatibility workaround:
# Houdini 20.5 ships USD 24.03 headers that fail to compile under
# Xcode 26 / AppleClang 21 because pxr/usd/sdf/childrenProxy.h contains an
# invalid _ValueProxy::operator= path that calls SdfChildrenProxy::_Set(),
# which does not exist. This target directly compiles Houdini USD geometry
# headers, so keep the workaround target-local and remove it when the
# Houdini/USD/toolchain combination compiles normally.
