This is for older CMakes which don't understand object libraries yet. We auto-generate a file at the top-level that references all the global plugin objects. Once they are referenced, the linker includes them into the final executable and their ctors run to register them with the plugin manager. By default this is on. Once we can require more recent CMakes, we can turn it off (and remove) in src/CMakeLists.txt.

// A work-around the problem that for static libraries unused globals
|
|
// aren't linked into the final binary. CMake automatically inserts
|
|
// code here to reference the globals that initializes each of the
|
|
// statically compiled plugins.
|
|
//
|
|
// Note: This won't be necessary anymore once we can assume CMake >2.8.8
|
|
// as a required depencendy. If so, switch bro_HAVE_OBJECT_LIBRARIES
|
|
// in src/CMakeLists.txt to TRUE and remove this.
