Some parts of config.log:

OPENSSL_INCLUDES=''

Looks like Tg-cli doesn't support LibreSSL. I can't find any other useful information even searching 'openssl/ssl.h' file not found.

Any ideas?

You need libssl-dev.

Perhaps this help you: "How to install libssl-dev ,libffi-dev on Mac os?"

brew link openssl --force does not work since it's macOS build-in software:

Warning: Refusing to link macOS-provided software: openssl@1.1
If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

Therefore, you need to do following steps:

$ export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
$ export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

The compilers can detect libssl now.

Unfortunately, dyld cannot find newer libssl library:

dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
  Referenced from: /***/***/tg/bin/tl-parser
