Subject: sigrok-native-macosx: Fix Homebrew package paths
X-Git-Url: https://sigrok.org/gitweb/?p=sigrok-util.git;a=commitdiff_plain;h=bf84662962e3876fffcf26a7f2f51d5d7699f697

sigrok-native-macosx: Fix Homebrew package paths

Use a more reliable method of determining paths to Homebrew formula prefixes,
`brew --prefix`. Use this to find pkg-config files for keg-only formulae,
now including libffi, which is required for glibmm.

This fixes bug #1367.
