Subject: [PATCH] gnu: meshlab: Update to 2022.02.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Note that the previous version no longer compiled (this one does).

* gnu/packages/engineering.scm (meshlab): Update to 2022.02.
[inputs]: Remove the no longer required qtscript and
qtxmlpatterns. Add (uncomment) qhull.
[arguments]: Use G-expressions.
<#:configure-flags>: Set the rpath to fix missing libraries (presumably
new since the previous version) detected during the 'validate-runpath'
phase.
<#:phases>: Remove trailing boolean from 'go-to-source-dir' phase.
Remove the 'move-files' phase, which was made redundant by the manually
provided rpath.
[description]: Move a word and add some commas to improve the
readability. Typeset a program name in @samp{}.
