roslaunch_add_file_check(..) and build dependencies

Having added a roslaunch_add_file_check(..) to my CMakeLists.txt, I notice that if the tests are invoked as:

catkin_make run_tests_my_package

in a clean workspace (ie: no build or devel directories present), all tests that include launchfiles that start compiled nodes fail. catkin immediately tries to execute the tests, without first compiling the package, or any of its dependencies. Example console output:

####
#### Running command: "make run_tests_my_package -j1" in "/home/user/ros/catkin_ws/build"
####
-- run_tests.py: execute commands
  /usr/bin/cmake -E make_directory /home/user/ros/catkin_ws/build/test_results/my_package
  /opt/ros/hydro/share/roslaunch/cmake/../scripts/roslaunch-check -o /home/user/ros/catkin_ws/build/test_results/my_package/roslaunch-check_tests_roslaunch_test.xml.xml /home/user/ros/catkin_ws/src/my_repo/my_package/tests/roslaunch_test.xml

...writing test results to /home/user/ros/catkin_ws/build/test_results/my_package/roslaunch-check_tests_roslaunch_test.xml.xml
FAILURE:

Built target run_tests_my_package_roslaunch-check_tests_roslaunch_test.xml
Built target run_tests_my_package_roslaunch-check
Built target run_tests_my_package

my_package has both run and build depends on some_other_package in its package.xml. And roslaunch is a build_depend of my_package.

I've tried using add_dependencies(..), but couldn't find a working target. It would also mean I'd have to manually make all targets dependencies of my roslaunch test. Is there a way to make the roslaunch tests only run after all other targets have been built?

The next roslaunch version (1.9.55) will allow you to specify the option keyword DEPENDENCIES when invoking roslaunch_add_file_check() followed by a list of target names which must be built before the test is run.

Until then you must manually build all targets necessary (or just build the whole workspace).

If a target local to my pkg is added to the DEPENDENCIES, and my pkg (build)depends on another pkg, will the targets in my dependencies also be build first? In other words: are the dependencies recursive?

Build dependencies from the package.xml file do not map to CMake target dependencies automatically since they are very different. If you want to depend on all target packages you depend on are exporting use the catkin_EXPORTED_TARGETS variable as an argument. Those are usually used for targets which generate message header etc.
