While building a program that uses openssl headers and libraries, the only way I was able to compile the program was to rely setting Always Search User Paths and modifying the Header Search Paths variable to point to the directory where the header files are located. Why is this Build Setting deprecated? What should I have done instead to help clang find the headers? I can't find any recent questions regarding this build setting.

Since switching to a Mac Studio and updating to Ventura (13.2.1, but happened with earlier Ventura releases), Music's broadcasts to four wired AirPlay Yamaha WXA-50 receivers/amps are subject to occasional dropouts. I haven't been able to characterize when they occur (death for debugging...I know...). My best guess for now is that other processes are getting prioritized over Music's worker bees. But that's purely a guess. It seems the dropouts occur most frequently during the last few seconds of a track. But that could be observational bias. Mostly, I'm fishing for others who might have noticed similar behavior and might have some theories on what's going on. Any comments?
