+# 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。
