\`configure' configures this package to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/PACKAGE]

              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  XMKMF       Path to xmkmf, Makefile generator for X Window System

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

# Like AC_CHECK_HEADER, but it uses the already-computed -I directories.

# Like AC_EGREP_HEADER, but it uses the already-computed -I directories.
#

# Like AC_COMPILE_IFELSE but it uses the already-computed -I directories.
#

# Like AC_CHECK_LIB, but it uses the already-computed -I and -L directories.
# Use this sparingly; it probably doesn't work very well on X programs.
#

# Like AC_RUN_IFELSE but it uses the already-computed -I directories.
# (But not the -L directories!)
#

# Usage: HANDLE_X_PATH_ARG([variable_name],
#                          [--command-line-option],
#                          [descriptive string])
#
# All of the --with options take three forms:
#
#   --with-foo (or --with-foo=yes)
#   --without-foo (or --with-foo=no)
#   --with-foo=/DIR
#
# This function, HANDLE_X_PATH_ARG, deals with the /DIR case.  When it sees
# a directory (string beginning with a slash) it checks to see whether
# /DIR/include and /DIR/lib exist, and adds them to $X_CFLAGS and $X_LIBS
# as appropriate.

      # The following arcana was gleaned from conversations with
      # Eric Schwartz <erics@col.hp.com>:
      #
      # On HPUX 10.x, the parts of X that HP considers "standard" live in
      # /usr/{include,lib}/X11R6/.  The parts that HP doesn't consider
      # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
      # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
      # Also, there are symlinks from /usr/include/ and /usr/lib/ into
      # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
      # you don't need any -I or -L arguments.
      #
      # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
      # are the same division as 10.x.  However, there are no symlinks to
      # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
      # arguments are always necessary.
      #
      # However, X11R6 was available on HPUX 9.x as a patch: if that
      # patch was installed, then all of X11R6 went in to
      # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
      #
      # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
      # whether R5 was available as a patch; R6 undoubtedly was not.)
      #
      # So.  We try and use the highest numbered pair of
      # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
      # that are available.  We do not mix and match different versions
      # of X.
      #
      # Question I still don't know the answer to: (do you?)
      #
      #   * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
      #     /usr/contrib/X11R6/ could be installed as a patch, what was in
      #     that contrib directory?  Did it contain so-called "standard"
      #     X11R6, or did it include Xaw and Xmu as well?  If the former,
      #     where did one find Xaw and Xmu on 9.x R6 systems?  Would this
      #     be a situation where one had to reach into the R5 headers and
      #     libs to find Xmu?  That is, must both R6 and R5 directories
      #     be on the -I and -L lists in that case?

# AX_PTHREAD is from the GNU Autoconf Archive.
# https://savannah.gnu.org/projects/autoconf-archive/
# ===========================================================================
#        https://www.gnu.org/software/autoconf-archive/ax_pthread.html
# ===========================================================================
#
# SYNOPSIS
#
#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro figures out how to build C programs using POSIX threads. It
#   sets the PTHREAD_LIBS output variable to the threads library and linker
#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
#   flags that are needed. (The user can also force certain compiler
#   flags/libs to be tested by setting these environment variables.)
#
#   Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
#   needed for multi-threaded programs (defaults to the value of CC
#   respectively CXX otherwise). (This is necessary on e.g. AIX to use the
#   special cc_r/CC_r compiler alias.)
#
#   NOTE: You are assumed to not only compile your program with these flags,
#   but also to link with them as well. For example, you might link with
#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#   $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
#   If you are only building threaded programs, you may wish to use these
#   variables in your default LIBS, CFLAGS, and CC:
#
#     LIBS="$PTHREAD_LIBS $LIBS"
#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
#     CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
#     CC="$PTHREAD_CC"
#     CXX="$PTHREAD_CXX"
#
#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
#   PTHREAD_CFLAGS.
#
#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
#   is not found. If ACTION-IF-FOUND is not specified, the default action
#   will define HAVE_PTHREAD.
#
#   Please let the authors know if this macro fails on any platform, or if
#   you have any other suggestions or comments. This macro was based on work
#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
#   grateful for the helpful feedback of numerous users.

# This is what autoupdate's m4 run will expand.  It fires
# the warning (with _au_warn_XXX), outputs it into the
# updated configure.ac (with AC_DIAGNOSE), and then outputs
# the replacement expansion.

# This is an auxiliary macro that is also run when
# autoupdate runs m4.  It simply calls m4_warning, but
# we need a wrapper so that each warning is emitted only
# once.  We break the quoting in m4_warning's argument in
# order to expand this macro's arguments, not AU_DEFUN's.

# Finally, this is the expansion that is picked up by
# autoconf.  It tells the user to run autoupdate, and
# then outputs the replacement expansion.  We do not care
# about autoupdate's warning because that contains
# information on what to do *after* running autoupdate.

#           (Note: HP C rejects this with "bad form for `-t' option")
# -pthreads: Solaris/gcc (Note: HP C also rejects)
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
#      doesn't hurt to check since this sometimes defines pthreads and
#      -D_REENTRANT too), HP C (must be checked before -lpthread, which

        # supports has POSIX threads in a separate library.  This tends not
        # to be the way of modern systems, but it's conceivable.)

        # (Note 2: On some systems, notably Darwin, -pthread is not needed
        # to get POSIX threads support; the API is always present and
        # active.  We could reasonably leave PTHREAD_CFLAGS empty.  But
        # -pthread does define _REENTRANT, and while the Darwin headers
        # ignore this macro, third-party headers might not.)

        # However, older versions of Clang make a point of warning the user
        # that, in an invocation where only linking and no compilation is
        # taking place, the -pthread option has no effect ("argument unused
        # during compilation").  They expect -pthread to be passed in only
        # when source code is being compiled.
        #
        # Problem is, this is at odds with the way Automake and most other
        # C build frameworks function, which is that the same flags used in
        # compilation (CFLAGS) are also used in linking.  Many systems
        # supported by AX_PTHREAD require exactly this for POSIX threads
        # support, and in fact it is often not straightforward to specify a
        # flag that is used only in the compilation phase and not in
        # linking.  Such a scenario is extremely rare in practice.
        #
        # Even though use of the -pthread flag in linking would only print
        # a warning, this can be a nuisance for well-run software projects

  #
  #   1.x: libGLESv1_CM
  #   2.x: libGLESv2
  #   3.x: libGLESv2 on Windows, libGLESv3 on Android
  #

  #
  #   libGL        - a superset of everything up to and including OpenGL 4.6
  #   libGLESv1_CM - OpenGLES 1.1, meaning it omits much of OpenGL 1.3
  #   libGLESv2    - OpenGLES 2 and 3, meaning it omits even more of OpenGL 1.3
  #

  #
  # Unless we are using --with-gles on Linux, in which case we are attempting
  # to simulate a system that does not natively support OpenGL 1.3.  In that
  # case, we use the v1 and/or v2 libraries instead.
  #
  # Common practice on Android seems to be to link against the v1, v2 and v3
  # libraries in order, and then do runtime checks to see which set of
  # functions is actually supported by the runtime.  Just because you linked
  # against a GLES3 library doesn't mean that the hardware supports it: most
