I installed curl using brew. I found that libcurl exists under: /opt/homebrew/Cellar/curl/7.76.1/lib
below is content of this dir:

question - how to make it to compile?
I can compile it on Windows & Linux.
Jonas Maebe:
Have you added that directory to the linker's library search path? (-Fl/opt/homebrew/Cellar/curl/7.76.1/lib) That directory is not a default directory in which the linker looks for libraries.

configured as you advised - same error
Jonas Maebe:
Looking at the source of that unit, it's missing a {$linklib curl} directive. I wonder why it was enabled for Darwin, since it was obviously never tested there.
(You can add that line to your program, it doesn't have to be in the unit itself)
