My ros2 package depends on an external .so file. What is the correct way to ship this package while also shipping the .so with the package. I am trying to avoid a system install of the .so file.

Following leads to link error (cannot find -lexternallib) when another package tries to depend on mypackage

install(FILES
  thirdparty/lib/libexternal_lib.so
  DESTINATION lib/
)

Appreciate any help.

If anyone else has this issue, got some pointers from link text. Following works

add_library(external_lib SHARED thirdparty/lib/libexternal_lib.so)
set_target_properties(external_lib PROPERTIES LINKER_LANGUAGE CXX)
ament_export_targets(external_libTargets HAS_LIBRARY_TARGET)
