1495	Optional Features:
1496	--disable-option-checking ignore unrecognized --enable/--with options
1497	--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1498	--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1499	--enable-silent-rules less verbose build output (undo: "make V=1")
1500	--disable-silent-rules verbose build output (undo: "make V=0")
1501	--enable-maintainer-mode
1502	enable make rules and dependencies not useful (and
1503	sometimes confusing) to the casual installer
1504	--enable-dependency-tracking
1505	do not reject slow dependency extractors
1506	--disable-dependency-tracking
1507	speeds up one-time build
1508	--enable-shared[=PKGS] build shared libraries [default=yes]
1509	--enable-static[=PKGS] build static libraries [default=yes]
1510	--enable-fast-install[=PKGS]
1511	optimize for fast installation [default=yes]
1512	--disable-libtool-lock avoid locking (might break parallel builds)
1513	--disable-tests do not build the test programs (default is to build)
1514	--disable-tools do not build the auxiliary tools (default is to
1515	build)
1516	--enable-werror[=OPT] Pass -Werror or the given argument to the compiler
1517	if it is supported
1518	--enable-unversioned-links
1519	Installed libpng header files are placed in a
1520	versioned subdirectory and installed libpng library
1521	(including DLL) files are versioned. If this option
1522	is enabled unversioned links will be created
1523	pointing to the corresponding installed files. If
1524	you use libpng.pc or libpng-config for all builds
1525	you do not need these links, but if you compile
1526	programs directly they will typically #include
1527	<png.h> and link with -lpng; in that case you need
1528	the links. The links can be installed manually using
1529	'make install-header-links' and 'make
1530	install-library-links' and can be removed using the
1531	corresponding uninstall- targets. If you do enable
1532	this option every libpng 'make install' will
1533	recreate the links to point to the just installed
1534	version of libpng. The default is to create the
1535	links; use --disable-unversioned-links to change
1536	this
1537	--enable-unversioned-libpng-pc
1538	Install the configuration file 'libpng.pc' as a link
1539	to the versioned version. This is done by default -
1540	use --disable-unversioned-libpng-pc to change this.
1541	--enable-unversioned-libpng-config
1542	Install the configuration file 'libpng-config' as a
1543	link to the versioned version. This is done by
1544	default - use --disable-unversioned-libpng-config to
1545	change this.
1546	--enable-hardware-optimizations
1547	Enable hardware optimizations: =no/off, yes/on.
1548	--enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api,
1549	yes/on. no/off: disable the optimizations; check:
1550	use internal checking code (deprecated and poorly
1551	supported); api: disable by default, enable by a
1552	call to png_set_option; yes/on: turn on
1553	unconditionally. If not specified: determined by the
1554	compiler.
1555	--enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api,
1556	yes/on. no/off: disable the optimizations; check:
1557	use internal checking code (deprecated and poorly

1561	compiler.
1562	--enable-mips-mmi Enable MIPS MMI optimizations: =no/off, check, api,
1563	yes/on. no/off: disable the optimizations; check:
1564	use internal checking code (deprecated and poorly
1565	supported); api: disable by default, enable by a
1566	call to png_set_option; yes/on: turn on
1567	unconditionally. If not specified: determined by the
1568	compiler.
1569	--enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on.
1570	no/off: disable the optimizations; yes/on: enable
1571	the optimizations. If not specified: determined by
1572	the compiler.
1573	--enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check,
1574	api, yes/on. no/off: disable the optimizations;
1575	check: use internal checking code; api: disable by
1576	default, enable by a call to png_set_option; yes/on:
1577	turn on unconditionally. If not specified:
1578	determined by the compiler.
1579	--enable-loongarch-lsx
1580	Enable LOONGARCH LSX optimizations: =no/off, yes/on:
1581	no/off: disable the optimizations; yes/on: turn on
1582	unconditionally. If not specified: determined by the
1583	compiler.
1584
1585	Optional Packages:
1586	--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1587	--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1588	--with-gnu-ld assume the C compiler uses GNU ld [default=no]
1589	--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
1590	both]
1591	--with-aix-soname=aix\|svr4\|both
1592	shared library versioning (aka "SONAME") variant to
1593	provide on AIX, [default=aix].
1594	--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
1595	compiler's sysroot if not specified).
1596	--with-zlib-prefix prefix that may have been used in installed zlib
1597	--with-pkgconfigdir Use the specified pkgconfig dir (default is
1598	libdir/pkgconfig)
1599	--with-binconfigs Generate shell libpng-config scripts as well as
1600	pkg-config data [default=yes]
1601	--with-libpng-prefix prefix libpng exported function (API) names with the
1602	given value
1603
1604	Some influential environment variables:
1605	CC C compiler command
1606	CFLAGS C compiler flags
1607	LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1608	nonstandard directory <lib dir>
1609	LIBS libraries to pass to the linker, e.g. -l<library>
1610	CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1611	you have headers in a nonstandard directory <include dir>
1612	CCAS assembler compiler command (defaults to CC)
1613	CCASFLAGS assembler compiler flags (defaults to CFLAGS)
1614	CPP C preprocessor
1615	LT_SYS_LIBRARY_PATH
1616	User-defined run-time library search path.
1617	AWK AWK language processor
1618	PNG_COPTS additional flags for the C compiler, to be used for options that
1619	would cause configure itself to fail
1620
1621	Use these variables to override the choices made by 'configure' or to help
1622	it to find libraries and programs with nonstandard names/locations.
