Hi, I have 2 robots with the same code. They are running on multiple machines(each robot on one machine). I have one node that needs to sync the data between them. The question is, how I change the topics on the launch so that each robot will work with its own topics and still be able to configure the topic of the syncing node so it will be able to subscribe from the second robot topics.
I'm using ROS 1 Kinetic

I have two ROS packages. Package A loads the library Mylib, which is a .so file. package B uses package A with find packages().

Package A compiles without any issues, while package B fails for the reason: cannot find -lMylib.

I don't understand why Mylib is required by package B if Package A loaded it without problems

---EDIT----

These are the Cmake Formats packageA

cmake_minimum_required(VERSION 2.8.3)
project(PackageA)
set(CMAKE_CXX_COMPILER_ID "--with-cc=/usr/bin/mpicc --with-cxx=/usr/bin/mpicxx -lmpi_cxx")

add_library(packageA_launcher src/PackageA_launcher.cpp)

packageB

cmake_minimum_required(VERSION 2.8.3) 
project(PackageB) 
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 ") 
find_package(catkin REQUIRED COMPONENTS
    cmake_modules

add_executable(some_PackageB_cpp
    src/some_PackageB_cpp.cpp        )
target_link_libraries(some_PackageB_cpp packageA_launcher  ${catkin_LIBRARIES} ) }

The error comes from package B.Package A compiles.

@mgruhler How can I say

"hey package B, just link against everything that package A links against"?

@mgruhler Exactly, it's a .so file located inside PackageA

Thanks! I Edited the question
