%description
This stack provides Python bindings for Qt. There are two providers: pyside
and pyqt. PySide is released under the LGPL. PyQt is released under the GPL.
Both the bindings and tools to build bindings are included from each available
provider. For PySide, it is called "Shiboken". For PyQt, this is called "SIP".
Also provided is adapter code to make the user's Python code independent of
which binding provider was actually used.
This is the humble (ROS 2) release of the python_qt_binding package, installed
under /opt/ros/humble.

# ROS 基座环境（chroot 已配置 ROS SIG repo；setup.sh 不存在时用守卫）

# 上游为 catkin 包（package.xml buildtool_depend=catkin），ROS 2 humble 无 catkin。
# catkin_python_setup() 的等价手动实现：直接调 setup.py build。
# setup.py 有 catkin_pkg 缺失时的 package.xml 解析 fallback，不依赖 catkin_pkg。

# 安装 Python 包到 ROS 前缀（catkin_python_setup install 的等价手动实现）

# 安装 cmake 辅助文件（CMakeLists.txt install(FILES cmake/... DESTINATION share/...) 的手动等价）
