Build fails during CircleCI process, but docker image can be built locally successfully

[JonSmet]

Summary

In the recent PR #153, the CircleCI process failed during the build when encountering an error for the ssc_pm_lexus package:

-- Could NOT find pacmod_msgs (missing: pacmod_msgs_DIR)
-- Could not find the required component 'pacmod_msgs'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.
CMake Error at /opt/ros/noetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "pacmod_msgs" with
  any of the following names:

    pacmod_msgsConfig.cmake
    pacmod_msgs-config.cmake

  Add the installation prefix of "pacmod_msgs" to CMAKE_PREFIX_PATH or set
  "pacmod_msgs_DIR" to a directory containing one of the above files.  If
  "pacmod_msgs" provides a separate development package or SDK, be sure it
  has been installed.

Expected Behavior

Both the CircleCI build process and a local build should complete successfully.

Actual Behavior

The CircleCI build process fails, but local builds complete successfully.

Steps to Reproduce the Actual Behavior

1. Run CircleCI process for carma-ssc-interface-wrapper repo.
2. Verify that build completes successfully; all packages are built
