%description
Compressed_image_transport provides a plugin to image_transport for transparently sending images
    encoded as JPEG by turbojpeg.

%build
# openEuler libjpeg-turbo-devel 虽 Provides turbojpeg-devel，但实际不含
# turbojpeg.h / libturbojpeg.so（仅 jpeglib.h + libjpeg.so），且无任何包提供
# libturbojpeg.so.0。故从 libjpeg-turbo 源码构建 libturbojpeg.a 静态库并
# 链入插件 .so（静态链接避免运行时依赖不存在的 libturbojpeg.so.0）。
# 关键修正：不再 install 到 /usr/include 与系统 libdir（build 阶段无写权限会
# Permission denied），改为暂存到构建树本地前缀，用 CPATH/LIBRARY_PATH
# 让 gcc 自动发现头文件与静态库，无需改 ROS 源码或 CMake 标志。

%changelog
* Wed Sep 23 2026 ai-importer <ai-importer@openeuler.org> - 0.1.3-1
- Initial import (ROS batch)
- Bundle libjpeg-turbo turbojpeg component (turbojpeg-devel not available in SP3)
- Fix round 4: stage libturbojpeg.a locally + CPATH/LIBRARY_PATH + PIC instead of
  installing to /usr/include during %build (Permission denied); static-link into plugin
