Subject: [PATCH] [CMake] Do not force CMAKE_OSX_DEPLOYMENT_TARGET (#2581)

This leaves the default of 10.15, but allows a user to change it in the
cache. When using Homebrew libraries on newer macOS version, the linker
emits warnings:

```
ld: warning: dylib (/opt/homebrew/lib/libSDL2.dylib) was built
for newer macOS version (13.0) than being linked (11.0)
```
