Subject: Build switches -Wall -Werror are only used if cmake switch WERROR is set to ON.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=2807b13d3c97eab1b7e257e8554c052a4a94775b;p=supertux.git

Build switches -Wall -Werror are only used if cmake switch WERROR is set to ON.
Some build environments ship broken header files, so SuperTux won't build with DEBUG ON there.
