I think this is because SRT needs to be able to access openssl from
homebrew. OpenSSL from homebrew is a keg-only.

Try running pkg-config to see more detail, you'll probably get somethings
like this:

# pkg-config --exists --print-errors srt
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'openssl', required by 'srt', not found

Look at the output of "brew info openssl", you will probably need to export
some environment variables so SRT can find the right openssl version.

Eg, mine is:

export PKG_CONFIG_PATH="/usr/local/opt/openssl at 1.1/lib/pkgconfig"
