make: Wildcards

 
 4.4 Using Wildcard Characters in File Names
 ===========================================
 
 A single file name can specify many files using "wildcard characters".
 The wildcard characters in 'make' are '*', '?' and '[...]', the same as
 in the Bourne shell.  For example, '*.c' specifies a list of all the
 files (in the working directory) whose names end in '.c'.
 
    The character '~' at the beginning of a file name also has special
 significance.  If alone, or followed by a slash, it represents your home
 directory.  For example '~/bin' expands to '/home/you/bin'.  If the '~'
 is followed by a word, the string represents the home directory of the
 user named by that word.  For example '~john/bin' expands to
 '/home/john/bin'.  On systems which don't have a home directory for each
 user (such as MS-DOS or MS-Windows), this functionality can be simulated
 by setting the environment variable HOME.
 
    Wildcard expansion is performed by 'make' automatically in targets
 and in prerequisites.  In recipes, the shell is responsible for wildcard
 expansion.  In other contexts, wildcard expansion happens only if you
 request it explicitly with the 'wildcard' function.
 
    The special significance of a wildcard character can be turned off by
 preceding it with a backslash.  Thus, 'foo\*bar' would refer to a
 specific file whose name consists of 'foo', an asterisk, and 'bar'.
