# Having a command like `find_package(catkin COMPONENTS roscpp)` in a package's CMakeLists.txt
# leads to adding "-Wl,-rpath=${RECIPE_SYSROOT}${ros_libdir}" option to the cross-linker.
# However starting from binutils 2.29 the cross-linker prepends this path with the value
# of --sysroot option thus producing wrong effective path (see https://sourceware.org/ml/binutils/2017-03/msg00161.html)
# These options help to aleviate the problem.
