+
+ Remove signals from find_package(Boost COMPONENTS ...) (#1580)
+
+ The packages use signals2, not signals. Only boost libraries with
+ compiled code should be passed to find_package(Boost COMPONENTS ...),
+ and the signals2 library has always been header only.
+
+ Boost 1.69 has removed the deprecated signals library, so the otherwise
+ useless but harmless `signals` component now breaks the build.
