Subject: configure.sh fix for visual studio
X-Git-Tag: v0.9.6~92
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=eb8b4d9a99146d9494d8d28402deb1fb4fe3202f;p=libvpx

configure.sh fix for visual studio

-For targets with external build systems like visual
studio CC is not set so check_add_cflags will fail.
Only call this function if extra_cflags is set.
