Bug#963933: glib2.0: autopkgtext: ld: cannot find -lcryptsetup

[Chris Hofstaedtler]

Source: glib2.0
Severity: serious
Version: 2.64.3-1

Dear glib2.0 Maintainers,

the autopkgtest suite offers quite interesting behaviour:
With an installed libcryptsetup-dev, ld fails with "cannot find
-lcryptsetup".

Log: https://ci.debian.net/data/autopkgtest/testing/amd64/g/glib2.0/6071882/log.gz

/usr/bin/ld: cannot find -lcryptsetup

I imagine this might be caused by libcryptsetup-dev not shipping an
.a library.

This prevents libmount1/util-linux to transition. Please investigate
and hopefully fix the problem at hand.

Thanks,
Chris
