I'm somewhat of a software developing noob. Please excuse that. Thanks for any help, and I'm not sure whether its my fault or cmake's or synergy's. Thanks.

@willem-hill
Try to open xcode first and if this is your first time, it should do some activation or asking for downloading tools.

This really looks like a support ticket. Please contact our support group.

For future reference... if you follow the compile instructions and get this error, you need to go into Xcode settings to the "locations" tab and choose the command line tools version you already installed (i think mine installed during the homebrew installation) and click ok or something. Doing this fixed this problem for me right away.

Thanks @koopatroopa120 - these instructions also worked for me. I just updated the wiki instructions to reflect this suggestion.

I changed the command line tools version.
But it still not work...
