unexpected warning from dylib

[David Barto]

My MacOS version is fully up to date 11.4, and my Xcode is fully up to date (12.5) and I’m seeing these warnings:

ld: warning: dylib (/opt/local/lib/libidn2.dylib) was built for newer macOS version (11.3) than being linked (11.0)
ld: warning: dylib (/opt/local/lib/libzstd.dylib) was built for newer macOS version (11.3) than being linked (11.0)
ld: warning: dylib (/opt/local/lib/libssl.dylib) was built for newer macOS version (11.2) than being linked (11.0)
ld: warning: dylib (/opt/local/lib/libcrypto.dylib) was built for newer macOS version (11.2) than being linked (11.0)

2 Questions:
1 - Why?
2 - How can I make them go away?
