+`configure' configures POV-Ray 3.7.0.10 to adapt to many kinds of systems.
+
+Usage: ./configure [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
+                          [/usr/local]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, `make install' will install all the files in
+`/usr/local/bin', `/usr/local/lib' etc.  You can specify
+an installation prefix other than `/usr/local' 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/povray]

+  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

+                          rendering (X Window only)
+  --enable-debug          enable compiler debugging mode
+  --enable-profile        enable program execution profiling
+  --enable-static         enable the linker to create static executable (no
+                          run-time dependancy to external libraries, larger
+                          binary)
+  --disable-optimiz       disable all compiler optimizations
+  --disable-optimiz-arch  disable architecture-specific compiler optimizations
+  --disable-pipe          disable usage of pipes during compilation (use
+                          temporary files instead)

+                          (larger binary)

+                          --enable-static)
+  --disable-io-restrictions
+                          disable POV-Ray's mechanism for control of I/O

+  --enable-silent-rules   less verbose build output (undo: "make V=1")
+  --disable-silent-rules  verbose build output (undo: "make V=0")
+  --enable-maintainer-mode
+                          enable make rules and dependencies not useful (and
+                          sometimes confusing) to the casual installer
+  --enable-dependency-tracking
+                          do not reject slow dependency extractors
+  --disable-dependency-tracking
+                          speeds up one-time build
+
+Optional Packages:
+  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --without-cygwin-dll    don't link with the Cygwin DLL (MinGW required)
+  --with-zlib[=DIR]       use the ZLIB library (in directory DIR)
+  --with-libpng[=DIR]     use the PNG library (in directory DIR)
+  --with-libjpeg[=DIR]    use the JPEG library (in directory DIR)
+  --with-libtiff[=DIR]    use the TIFF library (in directory DIR)
+  --with-libsdl[=DIR]     use the SDL library (in directory DIR)
+  --with-libmkl[=DIR]     use the Intel(R) Math Kernel Library (in directory
+                          DIR)
+  --with-openexr[=DIR]    use the OpenEXR library (in directory DIR)
+  --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-thread[=special-lib]
+                          use the Thread library from boost - it is possible
+                          to specify a certain library for the linker e.g.
+                          --with-boost-thread=boost_thread-gcc-mt
+  --with-x                use the X Window System
+
+Some influential environment variables:
+  COMPILED_BY customize the "unofficial version" message (required argument)
+  NON_REDISTRIBUTABLE_BUILD
+              see the installation documentation
+  C99_COMPATIBLE_RADIOSITY
+              adapt radiosity code to non-IEEE 754 floating point, requires
+              ISO C99 compiler and library (see octree.cpp for details)
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              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
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CXXCPP      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.
