    Could not find pkg-config information for EIGEN3.  It was not provided by
    the find-module for the package, nor was it explicitly passed into the call
    to ign_find_package(~).  This is most likely an error in this project's use
    of ign-cmake.
  Call Stack (most recent call first):

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
