Subject: CMakeLists.txt: Detect glibmm-2.68 in addition to glibmm-2.4
X-Git-Url: https://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=33c5ac28f73aa35c5fc4bbcf69a5ae61c0b50989

CMakeLists.txt: Detect glibmm-2.68 in addition to glibmm-2.4

On OS X with homebrew only glibmm-2.68 series is available. As far
as I can tell there are no breaking changes for PulseView on the
glibmm-2.68 ABI change.

This change still prefers glibmm-2.4 if found, and uses 2.4 if both
2.4 and 2.68 are available.
