Hello,

Thanks for your corrections to these two patches, and for integrating
the ~libe57format~ package.

For the ~cloudcompare~ package, I was also surprised by the joint use
of qt6 and qt5. I've just checked, it's an error on my part, the package
does compile with ~qtlocation-5~ input. I am attaching a corrected
version of this package.

As for the rest, I agree with you. It be better to replace the
submodules and external dependencies integrated in the sources. But I
don't really know how to do that. I did find some examples in other
packages, but it seems necessary to patch the ~cmake~ files, which I don't
really know how to do.
