Subject: Use gflags ALIAS instead of ${gflags_XXX} vars
X-Git-Tag: submit/tizen/20180313.064233~39^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1cae334a198010b7c4642dfb578552d2bf15adc;p=platform%2Fupstream%2Fglog.git

Use gflags ALIAS instead of ${gflags_XXX} vars

The gflags project updated their CMake config last year with a
`gflags` ALIAS target. This can be used instead of the legacy
`${gflags_LIBRARIES}` and `${gflags_INCLUDE_DIRS}` variables. It also
looks cleaner.

Fixes #198
