MPI_C not found, but installed

During the prepare step of axii upgrade in VisionX the following error occurs:

== Configuring target PointCloudViewerGuiPlugin ... ==

But running mpicc --version returns successfully an installed version (gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0).

Adding deps/vtk to the workspace also did not solve the problem

@plewnia thanks for reporting this. As you are using GCC 11, could you please provide more information about your system?

Also, please provide an error log with deps/vtk being in your workspace

I am using Ubuntu 22.04 and the error message stays exactly the same even after running axii w add deps/vtk and axii w upgrade -m deps/vtk:

-- Configuring incomplete, errors occurred!

As you see: It's not using the provided version in the workspace. Maybe we should investigate this on your PC.

I am having the same issue, it seems this is not an isolated problem.

Also, the problem occurred with a fresh axii installation and workspace at @aq6499_brogi's Ubuntu 22 notebook.
