1471	versioned subdirectory and installed libpng library
1472	(including DLL) files are versioned. If this option
1473	is enabled unversioned links will be created
1474	pointing to the corresponding installed files. If
1475	you use libpng.pc or libpng-config for all builds
1476	you do not need these links, but if you compile
1477	programs directly they will typically #include
1478	<png.h> and link with -lpng; in that case you need
1479	the links. The links can be installed manually using
1480	'make install-header-links' and 'make
1481	install-library-links' and can be removed using the
1482	corresponding uninstall- targets. If you do enable
1483	this option every libpng 'make install' will
1484	recreate the links to point to the just installed
1485	version of libpng. The default is to create the
1486	links; use --disable-unversioned-links to change
1487	this
1488	--enable-unversioned-libpng-pc
1489	Install the configuration file 'libpng.pc' as a link
1490	to the versioned version. This is done by default -
1491	use --disable-unversioned-libpng-pc to change this.
1492	--enable-unversioned-libpng-config
1493	Install the configuration file 'libpng-config' as a
1494	link to the versioned version. This is done by
1495	default - use --disable-unversioned-libpng-config to
1496	change this.
1497	--enable-hardware-optimizations
1498	Enable hardware optimizations: =no/off, yes/on:
1499	--enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api,
1500	yes/on: no/off: disable the optimizations; check:
1501	use internal checking code (deprecated and poorly
1502	supported); api: disable by default, enable by a
1503	call to png_set_option; yes/on: turn on
1504	unconditionally. If not specified: determined by the
1505	compiler.
1506	--enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api,
1507	yes/on: no/off: disable the optimizations; check:
1508	use internal checking code (deprecated and poorly
1509	supported); api: disable by default, enable by a
1510	call to png_set_option; yes/on: turn on
1511	unconditionally. If not specified: determined by the
1512	compiler.
1513	--enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on:
1514	no/off: disable the optimizations; yes/on: enable
1515	the optimizations. If not specified: determined by
1516	the compiler.
1517	--enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check,
1518	api, yes/on: no/off: disable the optimizations;
1519	check: use internal checking code api: disable by
1520	default, enable by a call to png_set_option yes/on:
1521	turn on unconditionally. If not specified:
1522	determined by the compiler.
1523
1524	Optional Packages:
1525	--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1526	--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1527	--with-gnu-ld assume the C compiler uses GNU ld [default=no]
1528	--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
1529	both]
1530	--with-aix-soname=aix\|svr4\|both
1531	shared library versioning (aka "SONAME") variant to
1532	provide on AIX, [default=aix].
1533	--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
1534	compiler's sysroot if not specified).
1535	--with-zlib-prefix prefix that may have been used in installed zlib
1536	--with-pkgconfigdir Use the specified pkgconfig dir (default is
1537	libdir/pkgconfig)
1538	--with-binconfigs Generate shell libpng-config scripts as well as
1539	pkg-config data [default=yes]
1540	--with-libpng-prefix prefix libpng exported function (API) names with the
1541	given value
1542
1543	Some influential environment variables:
1544	CC C compiler command
1545	CFLAGS C compiler flags
1546	LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1547	nonstandard directory <lib dir>
1548	LIBS libraries to pass to the linker, e.g. -l<library>
1549	CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1550	you have headers in a nonstandard directory <include dir>
1551	CCAS assembler compiler command (defaults to CC)
1552	CCASFLAGS assembler compiler flags (defaults to CFLAGS)
1553	CPP C preprocessor
1554	LT_SYS_LIBRARY_PATH
1555	User-defined run-time library search path.
1556	PNG_COPTS additional flags for the C compiler, use this for options that
1557	would cause configure itself to fail
1558
1559	Use these variables to override the choices made by `configure' or to help
1560	it to find libraries and programs with nonstandard names/locations.
