Subject: CMakeLists.txt: use check_c_source_runs instead of check_c_source_compiles
X-Git-Tag: 1.9.9-b1~694^2~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b8418eabf6b373c9a79a6ba847a90e9b984f033;p=thirdparty%2Fzlib-ng.git

CMakeLists.txt: use check_c_source_runs instead of check_c_source_compiles
to try to avoid using intrinsics and an instruction set the compiler
knows but the host CPU doesn't support.
