1518	--enable-aix-soname=aix\|svr4\|both
1519	shared library versioning (aka "SONAME") variant to
1520	provide on AIX, [default=aix].
1521	--disable-libtool-lock avoid locking (might break parallel builds)
1522	--disable-tests do not build the test programs (default is to build)
1523	--disable-tools do not build the auxiliary tools (default is to
1524	build)
1525	--enable-werror[=OPT] Pass -Werror or the given argument to the compiler
1526	if it is supported
1527	--enable-unversioned-links
1528	Installed libpng header files are placed in a
1529	versioned subdirectory and installed libpng library
1530	(including DLL) files are versioned. If this option
1531	is enabled unversioned links will be created
1532	pointing to the corresponding installed files. If
1533	you use libpng.pc or libpng-config for all builds
1534	you do not need these links, but if you compile
1535	programs directly they will typically #include
1536	<png.h> and link with -lpng; in that case you need
1537	the links. The links can be installed manually using
1538	'make install-header-links' and 'make
1539	install-library-links' and can be removed using the
1540	corresponding uninstall- targets. If you do enable
1541	this option every libpng 'make install' will
1542	recreate the links to point to the just installed
1543	version of libpng. The default is to create the
1544	links; use --disable-unversioned-links to change
1545	this
1546	--enable-unversioned-libpng-pc
1547	Install the configuration file 'libpng.pc' as a link
1548	to the versioned version. This is done by default -
1549	use --disable-unversioned-libpng-pc to change this.
1550	--enable-unversioned-libpng-config
1551	Install the configuration file 'libpng-config' as a
1552	link to the versioned version. This is done by
1553	default - use --disable-unversioned-libpng-config to
1554	change this.
1555	--enable-hardware-optimizations
1556	Enable hardware optimizations: =no/off, yes/on.
1557	--enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api,
1558	yes/on. no/off: disable the optimizations; check:
1559	use internal checking code (deprecated and poorly
1560	supported); api: disable by default, enable by a
1561	call to png_set_option; yes/on: turn on
1562	unconditionally. If not specified: determined by the
1563	compiler.
1564	--enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api,
1565	yes/on. no/off: disable the optimizations; check:
1566	use internal checking code (deprecated and poorly

1570	compiler.
1571	--enable-mips-mmi Enable MIPS MMI optimizations: =no/off, check, api,

1573	use internal checking code (deprecated and poorly
1574	supported); api: disable by default, enable by a
1575	call to png_set_option; yes/on: turn on
1576	unconditionally. If not specified: determined by the
1577	compiler.
1578	--enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on.
1579	no/off: disable the optimizations; yes/on: enable
1580	the optimizations. If not specified: determined by
1581	the compiler.
1582	--enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check,
1583	api, yes/on. no/off: disable the optimizations;
1584	check: use internal checking code; api: disable by
1585	default, enable by a call to png_set_option; yes/on:
1586	turn on unconditionally. If not specified:
1587	determined by the compiler.
1588	--enable-loongarch-lsx
1589	Enable LOONGARCH LSX optimizations: =no/off, yes/on:
1590	no/off: disable the optimizations; yes/on: turn on
1591	unconditionally. If not specified: determined by the
1592	compiler.
1593
1594	Optional Packages:
1595	--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1596	--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1597	--with-gnu-ld assume the C compiler uses GNU ld [default=no]
1598	--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
1599	compiler's sysroot if not specified).
1600	--with-zlib-prefix prefix that may have been used in installed zlib
1601	--with-pkgconfigdir Use the specified pkgconfig dir (default is
1602	libdir/pkgconfig)
1603	--with-binconfigs Generate shell libpng-config scripts as well as
1604	pkg-config data [default=yes]
1605	--with-libpng-prefix prefix libpng exported function (API) names with the
1606	given value
1607
1608	Some influential environment variables:
1609	CC C compiler command
1610	CFLAGS C compiler flags
1611	LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1612	nonstandard directory <lib dir>
1613	LIBS libraries to pass to the linker, e.g. -l<library>
1614	CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1615	you have headers in a nonstandard directory <include dir>
1616	CCAS assembler compiler command (defaults to CC)
1617	CCASFLAGS assembler compiler flags (defaults to CFLAGS)
1618	CPP C preprocessor
1619	LT_SYS_LIBRARY_PATH
1620	User-defined run-time library search path.
1621	AWK AWK language processor
1622	PNG_COPTS additional flags for the C compiler, to be used for options that
1623	would cause configure itself to fail
1624
1625	Use these variables to override the choices made by 'configure' or to help
1626	it to find libraries and programs with nonstandard names/locations.
