I am writing an application that outputs data to stdout and user messages (like the current progress) to stderr. As such i would like to print a progress bar to stderr.
Sadly this is currently not possible with the current master version. While you can set a custom stream in the settings, all the terminal interaction more or less assumes that the stream is stdout; or just ignores the setting completely (see show_console_cursor/erase_line).
This PR tries to fix that situation by letting the user pick explicitly between stdout/stderr.
I also set the cmake minimum to 3.12 to silence some warnings; let me know if you would like me to remove that.
