The cms-static, desktop-shell, hmi-controller, ivi-shell, and screen-share
modules use symbols from libexec_weston, e.g.:
$ ldd /usr/lib/x86_64-linux-gnu/weston/desktop-shell.so | grep "not found"
libexec_weston.so.0 => not found
Loading these modules from weston happens to work because the weston executable
itself links against libexec_weston, and has an rpath set. Still, these modules
depend on a library in a non-standard location. Adding an rpath could help
static checkers to make sure all shared objects' dependencies are present.
