Ninja runs just one command line for every build statement, so the Ninja generator needs to `&&`-chain multiple commands together into one long string. For long custom command sequences this can exceed the maximum command-line length for the operating system. In such cases, write the commands out to a script instead, and then run the script from Ninja's one command line. Co-Author: Brad King <brad.king@kitware.com> Fixes: #15612
