Subject: Bugfix: step-53 requires enabled DEAL_II_WITH_ZLIB
X-Git-Tag: v8.2.0-rc1~162^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b2c78fc2e891c684da737c36a4c41a2a3d1a062f;p=dealii.git

Bugfix: step-53 requires enabled DEAL_II_WITH_ZLIB

step-53 uses boost's <iostreams/filter/gzip.hpp> in order to unpack the
file topography.txt.gz.

If the internal boost variant is used this requires external linkage to
zlib.
