Hi,
I'm re-assigning this bug to libqalculate-dev based on the high similarity with
#1077798 .
Moreover, diffoscope-ing between libqalculate-dev_5.3.0-1_i386.deb and
libqalculate-dev_5.4.0.1-1_i386.deb :
│ │ ├── ./usr/lib/i386-linux-gnu/pkgconfig/libqalculate.pc
│ │ │ @@ -1,12 +1,12 @@
│ │ │ prefix=/usr

-I/usr/include/p11-kit-1 -I${includedir}
that's IMO an additional clue of this issue residing in libqalculate.
Please let me know otherwise.
Kind regards
