1495	--disable-option-checking ignore unrecognized --enable/--with options
1496	--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1497	--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1498	--enable-silent-rules less verbose build output (undo: "make V=1")
1499	--disable-silent-rules verbose build output (undo: "make V=0")
1500	--enable-maintainer-mode
1501	enable make rules and dependencies not useful (and
1502	sometimes confusing) to the casual installer
1503	--enable-dependency-tracking
1504	do not reject slow dependency extractors
1505	--disable-dependency-tracking
1506	speeds up one-time build
1507	--enable-shared[=PKGS] build shared libraries [default=yes]
1508	--enable-static[=PKGS] build static libraries [default=yes]
1509	--enable-fast-install[=PKGS]
1510	optimize for fast installation [default=yes]
1511	--disable-libtool-lock avoid locking (might break parallel builds)
1512	--disable-tests do not build the test programs (default is to build)
1513	--disable-tools do not build the auxiliary tools (default is to
1514	build)
1515	--enable-werror[=OPT] Pass -Werror or the given argument to the compiler
1516	if it is supported
1517	--enable-unversioned-links
1518	Installed libpng header files are placed in a
1519	versioned subdirectory and installed libpng library
1520	(including DLL) files are versioned. If this option
1521	is enabled unversioned links will be created
1522	pointing to the corresponding installed files. If
1523	you use libpng.pc or libpng-config for all builds
1524	you do not need these links, but if you compile
1525	programs directly they will typically #include
1526	<png.h> and link with -lpng; in that case you need
1527	the links. The links can be installed manually using
1528	'make install-header-links' and 'make
1529	install-library-links' and can be removed using the
1530	corresponding uninstall- targets. If you do enable
1531	this option every libpng 'make install' will
1532	recreate the links to point to the just installed
1533	version of libpng. The default is to create the
1534	links; use --disable-unversioned-links to change
1535	this
1536	--enable-unversioned-libpng-pc
1537	Install the configuration file 'libpng.pc' as a link
1538	to the versioned version. This is done by default -
1539	use --disable-unversioned-libpng-pc to change this.
1540	--enable-unversioned-libpng-config
1541	Install the configuration file 'libpng-config' as a
1542	link to the versioned version. This is done by
1543	default - use --disable-unversioned-libpng-config to
1544	change this.
1545	--enable-hardware-optimizations
1546	Enable hardware optimizations: =no/off, yes/on:
1547	--enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api,
1548	yes/on: no/off: disable the optimizations; check:
1549	use internal checking code (deprecated and poorly
1550	supported); api: disable by default, enable by a
1551	call to png_set_option; yes/on: turn on
1552	unconditionally. If not specified: determined by the
1553	compiler.
1554	--enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api,
1555	yes/on: no/off: disable the optimizations; check:
1556	use internal checking code (deprecated and poorly
1557	supported); api: disable by default, enable by a
1558	call to png_set_option; yes/on: turn on
1559	unconditionally. If not specified: determined by the
1560	compiler.
1561	--enable-mips-mmi Enable MIPS MMI optimizations: =no/off, check, api,
1562	yes/on: no/off: disable the optimizations; check:
1563	use internal checking code (deprecated and poorly
1564	supported); api: disable by default, enable by a
1565	call to png_set_option; yes/on: turn on
1566	unconditionally. If not specified: determined by the
1567	compiler.
1568	--enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on:
1569	no/off: disable the optimizations; yes/on: enable
1570	the optimizations. If not specified: determined by
1571	the compiler.
1572	--enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check,
1573	api, yes/on: no/off: disable the optimizations;
1574	check: use internal checking code api: disable by
1575	default, enable by a call to png_set_option yes/on:
1576	turn on unconditionally. If not specified:
1577	determined by the compiler.
1578	--enable-loongarch-lsx
1579	Enable LOONGARCH LSX optimizations: =no/off, yes/on:
1580	no/off: disable the optimizations; yes/on: turn on
1581	unconditionally. If not specified: determined by the
1582	compiler.
1583
1584	Optional Packages:
1585	--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1586	--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1587	--with-gnu-ld assume the C compiler uses GNU ld [default=no]
1588	--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
1589	both]
1590	--with-aix-soname=aix\|svr4\|both
1591	shared library versioning (aka "SONAME") variant to
1592	provide on AIX, [default=aix].
1593	--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
1594	compiler's sysroot if not specified).
1595	--with-zlib-prefix prefix that may have been used in installed zlib
1596	--with-pkgconfigdir Use the specified pkgconfig dir (default is
1597	libdir/pkgconfig)
1598	--with-binconfigs Generate shell libpng-config scripts as well as
1599	pkg-config data [default=yes]
1600	--with-libpng-prefix prefix libpng exported function (API) names with the
1601	given value
1602
1603	Some influential environment variables:
1604	CC C compiler command
1605	CFLAGS C compiler flags
1606	LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1607	nonstandard directory <lib dir>
1608	LIBS libraries to pass to the linker, e.g. -l<library>
1609	CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1610	you have headers in a nonstandard directory <include dir>
1611	CCAS assembler compiler command (defaults to CC)
1612	CCASFLAGS assembler compiler flags (defaults to CFLAGS)
1613	CPP C preprocessor
1614	LT_SYS_LIBRARY_PATH
1615	User-defined run-time library search path.
1616	PNG_COPTS additional flags for the C compiler, use this for options that
1617	would cause configure itself to fail
1618
1619	Use these variables to override the choices made by 'configure' or to help
1620	it to find libraries and programs with nonstandard names/locations.
