Compilation issue with macOS SDK 12.3

[Jérémie Dumas]

Hi there. When trying to build Tracy (wolfpld/tracy#368) on a recently upgraded macOS, I encountered the following compilation issue with NFD:

cd /Users/jedumas/external/git/nativefiledialog-extended/build/src && /Applications/Xcode12.4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -I/Users/jedumas/external/git/nativefiledialog-extended/src/include -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk -nostdlib -fno-exceptions -fno-rtti -MD -MT src/CMakeFiles/nfd.dir/nfd_cocoa.m.o -MF CMakeFiles/nfd.dir/nfd_cocoa.m.o.d -o CMakeFiles/nfd.dir/nfd_cocoa.m.o -c /Users/jedumas/external/git/nativefiledialog-extended/src/nfd_cocoa.m

To reproduce, specify the OSX_SYSROOT folder when calling CMake:

cmake -DCMAKE_OSX_SYSROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/ ..

Thanks for reporting the issue, I'll take a look. It builds fine on the GitHub hosted runners though, so perhaps they aren't using the latest SDK.

As per my comment in the tracy issue, there are two issues at play here - the use of an old version of Apple Clang, and the allowedFileTypes deprecation.

The allowedFileTypes deprecation will be tracked separately in #58. I'll close this issue for now, but do reopen it if the macOS 12 SDK still won't compile even after you have updated your compiler.
