Explicitly write out executable name

While using ${PROJECT_NAME} for simple single-executable projects
isn't an awful idea, it scales poorly. If you want to add tests or
a library or any other targets, it becomes awkward to keep using
${PROJECT_NAME} with various prefixes and suffixes to ensure all
targets have unique names. The readability benefits of spelling out
the name outweight the potential copy-paste-ability of using
${PROJECT_NAME} to name your executable.
