Build fails on SSE4.2 features required for x86_64

[petertorelli]

Hi Matt,

Using clang on big sur:

% gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.28)
Target: x86_64-apple-darwin20.2.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

And then.

% cmake ..

% make

The CMake did not support Clang, only gcc. Fixed in main (version 0.2.2).

Confirmed, thanks!
