Build using fresh installation fails on libxml2

[Boulder08]

I just did a fresh install of m-ab-s, but the build process fails on the first tool.

And the cmake log:

  It fails with the following output:

Can you try to see if it works on https://github.com/1480c1/media-autobuild_suite/tree/revert_ccache ?
