From: Moritz Warning Date: Wed, 6 Mar 2019 21:26:50 +0000 (+0100) Subject: cmake: match warnings more strictly in C++ feature checks X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7fc4dd3611d1569db99444425feaddc545699c06;p=openwrt%2Fstaging%2Fldir.git cmake: match warnings more strictly in C++ feature checks Require the word "warning" to appear at the start of a line, after whitespace, or after a `:`. This is the same that CTest launchers use to match warnings. It avoids matching "warning" inside file paths. Fixed in cmake 3.14.0.
