Configure $APP_NAME prior to building.
--help This help.
--ostype=OS Use one of the OS presets. May be one of:
debian, macosx, linux, freebsd, openbsd, netbsd
--prefix=DIR Prefix where $APP_NAME should be installed.
Default is $PREFIX
--sysconfdir=DIR Location where the config file should be installed.
Default is \$PREFIX/etc/$APP_DIRNAME
--libdir=DIR Location where the server files should be stored.
Default is \$PREFIX/lib
--datadir=DIR Location where the server data should be stored.
Default is \$PREFIX/var/lib/$APP_DIRNAME
--lua-version=VERSION Use specific Lua version: 5.2, 5.3, or 5.4
Default is auto-detected.
--lua-suffix=SUFFIX Versioning suffix to use in Lua filenames.
Default is "$LUA_SUFFIX" (lua$LUA_SUFFIX...)
--with-lua=PREFIX Use Lua from given prefix.
Default is auto-detected (the parent directory of \$LUA_BINDIR).
--with-lua-bin=DIR You can also specify Lua's bin dir.
Default is the directory of the auto-detected Lua interpreter,
or \$LUA_DIR/bin if --with-lua is used.
--runwith=BINARY What Lua binary to set as runtime environment.
Default is $RUNWITH
--with-lua-include=DIR You can also specify Lua's includes dir.
Default is \$LUA_DIR/include
--with-lua-lib=DIR You can also specify Lua's libraries dir.
Default is \$LUA_DIR/lib
--with-idn=LIB The name of the IDN library to link with.
Default is $IDN_LIB
--idn-library=(idn|icu) Select library to use for IDNA functionality.
idn: use GNU libidn
icu: use ICU from IBM (default)
--with-ssl=LIB The name of the SSL to link with.
Default is $OPENSSL_LIB
--with-random=METHOD CSPRNG backend to use. One of
getrandom: Linux kernel
arc4random: OpenBSD kernel
openssl: OpenSSL RAND method
Default is to use /dev/urandom
--cflags=FLAGS Flags to pass to the compiler
Default is $CFLAGS
--add-cflags=FLAGS Adds additional CFLAGS, preserving defaults.
Can be repeated.
--ldflags=FLAGS Flags to pass to the linker
Default is $LDFLAGS
--add-ldflags=FLAGS Adds additional linker flags, preserving defaults.
Can be repeated.
--c-compiler=CC The C compiler to use when building modules.
Default is $CC
--compiler-wrapper=WRAPPER Adds a prefix to compiler and linker calls,
usable for eg distcc or ccache.
--linker=CC The linker to use when building modules.
Default is $LD
--no-example-certs Disables generation of example certificates.
