'configure' configures MKVToolNix 96.0 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 '..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

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]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/mkvtoolnix]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]
  --target=TARGET   configure for building compilers for TARGET [HOST]

  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-update-check   If enabled, the GUI will check online for available
                          updates daily by downloading a small XML file from
                          the MKVToolNix home page (default: yes)
  --enable-mkvtoolnix     If enabled, the 'mkvtoolnix' wrapper binary will be
                          built (default: no)
  --enable-debug          compile with debug information (no)
  --enable-profiling      compile with profiling information (no)

  --enable-addrsan        compile with address sanitization turned on (no)
  --enable-ubsan          compile with sanitization for undefined behavior
                          turned on (no)
  --enable-precompiled-headers
                          enable the generation and use of precompiled headers

  --enable-gui            compile the Qt-based GUI (yes)
  --enable-dbus           compile DBus support (auto)

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-words=endianness set endianness (big or little)
  --with-extra-includes=DIR
                          Path to other include directories separated by ';'
  --with-extra-libs=DIR   Path to other library directories separated by ';'
  --with-drmingw=path     use link against Dr. MinGW's crash reporting library
                          found in path
  --without-flac          do not build with flac support
  --with-qmake6=prog      use prog instead of looking for qmake6
  --with-boost[=ARG]      use Boost library from a standard location
                          (ARG=yes), from the specified location (ARG=<path>),
                          or disable it (ARG=no) [ARG=yes]
  --with-boost-libdir=LIB_DIR
                          Force given directory for boost libraries. Note that
                          this will override library path detection, so use
                          this parameter only if default library detection
                          fails and you know exactly where your boost
                          libraries are located.
  --with-boost-filesystem[=special-lib]
                          use the Filesystem library from boost - it is
                          possible to specify a certain library for the linker
                          e.g. --with-boost-filesystem=boost_filesystem-gcc-mt
  --with-docbook-xsl-root=dir
                          use dir as base for DocBook XSL stylesheets instead
                          of looking for it; must contain the
                          "manpages/docbook.xsl" sub-directory and file
  --with-xsltproc=prog    use prog instead of looking for xsltproc
  --without-dvdread       do not build with libdvdread for reading chapters
                          from DVDs
  --with-po4a=prog        use prog instead of looking for po4a
  --without-gettext       do not build with gettext support

# SYNOPSIS
#
#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
#   Test for the Boost C++ libraries of a particular version (or newer)
#
#   If no path to the installed boost library is given the macro searchs
#   under /usr, /usr/local, /opt and /opt/local and evaluates the
#   $BOOST_ROOT environment variable. Further documentation is available at
#   <http://randspringer.de/boost/index.html>.
#
#   This macro calls:
#
#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
#
#   And sets:
