I have a workspace with 3 packages: an rqt plugin written in C++ (package A), a package with two custom messages (package B), and another C++ package (package C).
Packages A and C both rely on the custom messages defined in package B. To ensure that the dependencies for the executables in packages A and C are met, I have added the following line for each applicable executable:
`add_dependencies(executable_name ${catkin_EXPORTED_TARGETS})
`
Unfortunately, when I try to compile using `catkin_make`, I get an error saying that the header file for the messages don't exist. I'm fairly certain this error is coming from package A, the rqt plugin, since doing a catkin_make on package C alone generates no errors and successfully compiles the header files for the messages before trying to compile the executables (and catkin_make on the entire workspace works just fine after that since the header files have already been generated).
How do I go about telling catkin that the rqt plugin depends on the message files? I already have the message package name listed in the CMakeLists.txt file for the plugin as `find_package(catkin REQUIRED COMPONENTS package_b)` but that doesn't resolve the issue.
I'm currently compiling in ROS Kinetic but this issue existed in Indigo as well before I upgraded.
Any help would be appreciated.
