Finding PCL dependency fails in Dev environment built with Dockerfile.x86_64

I used run_dev.sh to build the base Docker image on the host platform (x86_64).
I then built another Docker image layer on top of this base image that includes debian install of the pcl packages:

RUN apt-get update && apt-get install -y \
    [...]
    ros-humble-pcl-conversions \
    ros-humble-pcl-msgs \

However, when then building a set of my own ros2 packages with colcon build (inside the Docker container as part of another Dockerfile image layer on top), which contain a dependency on PCL and have the corresponding build depends, find()s, and includes in package.xml/CMakeLists.txt, I get the following Cmake build error:

Imported target "MPI::MPI_C" includes non-existent path
    "/opt/hpcx/ompi/lib/x86_64-linux-gnu/openmpi/include"
  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.
  * An install or uninstall procedure did not complete successfully.
  * The installation package was faulty and references files it does not
  provide.

gmake: *** [Makefile:308: cmake_check_build_system] Error 1

Notably:

• This error did not occur before the switch to Isaac-ROS 3 and the change of the 'run_dev' build process.
• This error does not occur when compiled for arm64 with the "Dockerfile.aarch64" and the rest being the same set of build steps.

Read run_dev.sh and compare Dockerfile.x86_64 with Dockerfile.aarch64, focusing on how the base image is built. Trace the failure from CMakeLists.txt line 19 through PCLConfig.cmake and FindMPI.cmake. Done means an x86_64 Docker-based colcon build can find PCL without the missing MPI include path error.
