make(1) - GNU make utility to maintain groups of programs
make  executes  commands  in  the  makefile to update one or more target names, where name is typically a
program.  If no -f option is present, make  will  look  for  the  makefiles  GNUmakefile,  makefile,  and
Makefile, in that order.
-b, -m
     These options are ignored for compatibility with other versions of make.
-B, --always-make
     Unconditionally make all targets.
-C dir, --directory=dir
     Change to directory dir before reading the makefiles or doing anything else.  If multiple -C options
     are  specified,  each  is  interpreted relative to the previous one: -C / -C etc is equivalent to -C
     /etc.  This is typically used with recursive invocations of make.
-d   Print debugging information in addition to normal processing.  The debugging information says  which
     files  are being considered for remaking, which file-times are being compared and with what results,
     which files actually need  to  be  remade,  which  implicit  rules  are  considered  and  which  are
     applied---everything interesting about how make decides what to do.
--debug[=FLAGS]
     Print  debugging  information  in addition to normal processing.  If the FLAGS are omitted, then the
     behavior is the same as if -d was specified.  FLAGS may be a for all debugging output (same as using
     -d),  b for basic debugging, v for more verbose basic debugging, i for showing implicit rules, j for
     details on invocation of commands, and m for debugging while remaking makefiles.
-e, --environment-overrides
     Give variables taken from the environment precedence over variables from makefiles.
-f file, --file=file, --makefile=FILE
     Use file as a makefile.
-i, --ignore-errors
     Ignore all errors in commands executed to remake files.
-I dir, --include-dir=dir
     Specifies a directory dir to search for included makefiles.  If  several  -I  options  are  used  to
     specify  several  directories,  the  directories  are  searched  in the order specified.  Unlike the
     arguments to other flags of make, directories given with -I flags may come directly after the  flag:
     -Idir  is  allowed,  as  well  as  -I  dir.   This  syntax  is  allowed for compatibility with the C
     preprocessor's -I flag.
-j [jobs], --jobs[=jobs]
     Specifies the number of jobs (commands) to run simultaneously.  If there is more than one -j option,
     the  last  one is effective.  If the -j option is given without an argument, make will not limit the
     number of jobs that can run simultaneously.
-k, --keep-going
     Continue as much as possible after an error.  While the target that failed, and those that depend on
     it, cannot be remade, the other dependencies of these targets can be processed all the same.
-l [load], --load-average[=load]
     Specifies  that  no  new  jobs (commands) should be started if there are others jobs running and the
     load average is at least load (a floating-point number).  With no argument, removes a previous  load
     limit.
-L, --check-symlink-times
     Use the latest mtime between symlinks and target.
-n, --just-print, --dry-run, --recon
     Print the commands that would be executed, but do not execute them.
-o file, --old-file=file, --assume-old=file
     Do not remake the file file even if it is older than its dependencies, and do not remake anything on
     account of changes in file.  Essentially the file is treated as very old and its rules are ignored.
-p, --print-data-base
     Print the data base (rules and variable values)  that  results  from  reading  the  makefiles;  then
     execute  as  usual or as otherwise specified.  This also prints the version information given by the
     -v switch (see below).  To print the data base without trying to  remake  any  files,  use  make  -p
     -f/dev/null.
-q, --question
     ``Question  mode''.   Do not run any commands, or print anything; just return an exit status that is
     zero if the specified targets are already up to date, nonzero otherwise.
-r, --no-builtin-rules
     Eliminate use of the built-in implicit rules.  Also clear out  the  default  list  of  suffixes  for
     suffix rules.
-R, --no-builtin-variables
     Don't define any built-in variables.
-s, --silent, --quiet
     Silent operation; do not print the commands as they are executed.
-S, --no-keep-going, --stop
     Cancel  the  effect  of  the -k option.  This is never necessary except in a recursive make where -k
     might be inherited from the top-level make via MAKEFLAGS or if you  set  -k  in  MAKEFLAGS  in  your
     environment.
-t, --touch
     Touch  files  (mark them up to date without really changing them) instead of running their commands.
     This is used to pretend that the commands were done, in order to fool future invocations of make.
-v, --version
     Print the version of the make program plus a copyright, a list of authors and a notice that there is
     no warranty.
-w, --print-directory
     Print  a  message  containing  the working directory before and after other processing.  This may be
     useful for tracking down errors from complicated nests of recursive make commands.
--no-print-directory
     Turn off -w, even if it was turned on implicitly.
-W file, --what-if=file, --new-file=file, --assume-new=file
     Pretend that the target file has just been modified.  When used with the -n  flag,  this  shows  you
     what  would  happen if you were to modify that file.  Without -n, it is almost the same as running a
     touch command on the given file before running make, except that the modification  time  is  changed
     only in the imagination of make.
--warn-undefined-variables
     Warn when an undefined variable is referenced.
