Obviously for my use case it does look like a
reasonable alternative is to use file(GLOB...) followed by a check of
the result variable to see if it is empty. But implementation of an
additional IF subcommand called IS_FILE which just checks for the
existence of the specified file would do this in fewer lines and does
Precisely the purpose of
if(EXISTS ${file})
I think.
Thanks, Eric. EXISTS is what I needed.
I still think adding the qualifying phrase "if it exists or not" to the
IS_ABSOLUTE documentation would be useful.
I'd rather IS_ABSOLUTE did not force the file to exist.
I use it to check if some paths are absolute, regardless of whether they
exist.
