Chomp needs to depend on cmake_modules.

[clalancette]

Description

Fix the chomp package.xml to depend on cmake_modules, which is necessary to fix binary builds for it on the Melodic buildfarm. An example problem is here: http://build.ros.org/view/Mbin_ds_dS64/job/Mbin_ds_dS64__moveit_planners_chomp__debian_stretch_amd64__binary/56/consoleFull

Checklist

• [ N/A ] Required: Code is auto formatted using clang-format
• [ N/A ] Extended the tutorials / documentation, if necessary reference
• [ N/A ] Include a screenshot if changing a GUI
• [ N/A ] Optional: Created tests, which fail without this PR reference
• Optional: Decide if this should be cherry-picked to other current ROS branches (Indigo, Jade, Kinetic) - shouldn't be necessary, as chomp is only released in Melodic.

Thanks, actually there are similar issues with other dependencies that are find_package-d. Wouldn't those come up on the next build? ... Scratch that, I think I overlooked a few declarations.

I'll also cherry-pick this to kinetic.

@bmagyar Looks like you cherry-picked only to your clone. I did it for ros-planning.

Done and done :) Thanks for double checking
