Subject: CMake: Fix EXTRA_CFLAGS after commit 29d7856. [skip appveyor]
X-Git-Url: https://git.tcpdump.org/libpcap/commitdiff_plain/815b367d5bafe2bebcc0aa6ff8f54f21c4efafc5

CMake: Fix EXTRA_CFLAGS after commit 29d7856. [skip appveyor]

check_and_add_compiler_option() takes a string, not a variable. Get it
right this time and run CMake builds with a warnings guard again.
