Subject: Don't specify --version-script on Apple platforms in CMakeLists.txt.
X-Git-Tag: v1.2.7.1~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=27b772322237cfbbb8ebe6d9e0ca029312c5401e;p=thirdparty%2Fzlib-ng.git

Don't specify --version-script on Apple platforms in CMakeLists.txt.

Mac OS X's linker (derived from LLVM, not GNU binutils) does not support
--version-script. Don't specify it on this platform.
