LibreCAD: Build failure due to muparser

[mf2k (Frank Schima)]

Due to r118673 LibreCAD no longer builds on the buildbots because it cannot find muparser:

Using your patch from here​, it still fails when the muparser port is not installed.

Latest main.log

[anddam (Andrea D'Amore)]

I'm still getting this error on 10.11 with LibreCAD @2.0.8_0 with boost (see #42555) and muparser ports installed.

I see the port is building its own muparser library (build_muparser=true at config phase) but then qmake cannot find the related package. Is it possible to switch to the macports provided muparser?

It's advisable anyway and the mp-installed packages are correctly being found.

Here's an excerpt of the missing muparser:

	Updating '/opt/local/var/macports/build/_opt_macports_trunk_dports_cad_LibreCAD/LibreCAD/work/LibreCAD-2.0.8/librecad/src/../ts/librecad_ar.qm'...

See my log attachment:and.damore-main.log:ticket:42555​.

As further note even if there's the muParser error the resulting application bundle correctly works, see #50119.
