+Subject: [PATCH] Fix detection of ROS build
+
+CMAKE_PREFIX_PATH is not an environment variable, but CMake's
+internal one that contains a list of items (strings). This
+list needs to be concattenated into a single string in order
+to become "match"-able against a regex.

+Subject: [PATCH] realsense-camera: don't ignore linker flags set by user
+
+Yocto's bitbake sets global LDFLAGS that include the option
+--hash-style=gnu. If this option is ignored then bitbake's
+QA checks report that
+
+QA Issue: No GNU_HASH in the elf binary: '/[...]/opt/ros/indigo/lib/librealsense_camera_nodelet.so' [ldflags]
+
+The patch includes user defined linker flags to
+CMAKE_SHARED_LINKER_FLAGS defined in the project's CMakeList.txt.
