+
+ Remove `signals` from find_package(Boost COMPONENTS ...).
+
+ tf2 is using signals2, which is not the same library.
+ Additionally, signals2 has always been header only, and header only
+ libraries must not be listed in find_package.
+
+ Boost 1.69 removed the old signals library entirely, so the otherwise
+ useless `COMPONENTS signals` actually breaks the build.
