Drop hard Xcode dependency
XCODE_VERSION calls out to xcodebuild
, which is only available
when having Xcode
installed. The CommandLineTools are not
sufficient. To install Xcode, you must have an apple id to download
the Xcode.xip from apple.
We do not use xcodebuild anywhere in our build explicilty. At best it appears to be a proxy for checking the linker or the compiler. These should rather be done with
xcrun ld -version
or similar, and not by proxy through Xcode. The CLR should be sufficient for building software on macOS.
