Building on MAC Osx 11 (Big Sur) Xcode 12.2

• Nov 23, 2020 - 10:21

On Osx 11 sdk the MacOSX10.15.sdk is gone away replaced by MacOSX.sdk wich is symlinked to MacOSX11.0.sdk
as a consequence the build make step checking dependencies fails looking for MacOSX10.15.sdk
'greping' hère and there through build files I didn't see any reference to MacOSX10.15.sdk dependency so my question here is : where does the MacOSX10.15.sdk come from in make stuff ??

The trivial workaround here consists in creating a MacOSX10.15.sdk symlink to MacOSX.sdk in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs to make the build happen (need to sudo for that)

As soon as this symlink has been set the make process works as expected and I did not see any problems debugging the MuseScore App either in Qt creator or in Xcode

So my question again : where does the MacOSX10.15.sdk dependency come from in make stuff ??
