I am using CMake to compile and link some command-line tools that I have written (in C). My development machine is MacOS 10.15 Catalina.

I require the command-line tools to be able to run under MacOS High Sierra (10.13).

What changes do I need to make to my build environment to be able to achieve this?

At present, there is nothing in my CMakeLists that specifically targets Catalina, so I am unsure as to what I am doing wrong.

I have a Mojave machine and I know that these tools will run under Mojave.
