Subject: CMakeLists.txt: consistent whitespace in atomics check
X-Git-Url: http://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=d56edfc6b108b662a49e795b6af8df42ab6fb296

CMakeLists.txt: consistent whitespace in atomics check

Previous CMakeLists.txt rules used to mix TAB and SPACE indentation.
Consistently use TAB instead. This amends commit 4da54b6be6a1 which
introduced the check for the atomics library.

[ no change in behaviour, see whitespace ignoring diff to verify ]
