NAME
       make-first-existing-target - runs make on one of several targets

SYNOPSIS
       make-first-existing-target [-c cmd] target1 [target2 ...] --
       [make-options]

DESCRIPTION
       The design of make(1) causes difficulty when you know that a Makefile
       probably has one of several standardized target names, and want build
       machinery to run exactly one of them, propagating any errors. make(1)
       will exit 2 if a target does not exist, but an existing target may also
       exit 2 due to some other failure. Makefiles cannot be reliably parsed
       to find targets by anything less Turing-complete than make, and make
       itself does not provide a way to enumerate the targets in a Makefile.
       It may not even be possible to enumerate the targets in a Makefile
       without executing part of it. (Proof of this is left as an exercise for
       the reader.)

       This program avoids the problems described above, by attempting to call
       each specified target in turn, until it observes make actually doing
       something for one of them.

OPTIONS
       -c cmd
           This can be used to specify the make command to run. Default is
           "make".

EXIT STATUS
       The exit status is 0 if at least one target existed and was
       successfully run, and nonzero otherwise.
