I don't understand how to use system libaom. I had stuck
to using
system ffmpeg by disabling the whole "thirdparty".
Well, I think we better to clarify that
--without-Piece disables part of cingg AND
internal version of library (AND system wide linking?)
so, --without-lv2 disables any attempt at use
lv2 support code.
--disable-Piece AND --with-Piece only disables
building internal library version part, leaving it up to
system to provide headers and libs.
so you can specify BOTH --with-lv2 and
--disable-lv2 and this will mean "use system version of lv2"
-( sadly currently not working on Phyllis's Fedora multiarch
system ?)
--disable-Piece AND --without-Piece disables
both building of int. copy and linking/using of this code part
--disable-libdav1d will turn off building
internal copy of libdav1d but you can still pass flags
enabling use of system libdav1d.
Issues is a bit complicated by fact that some
libs needed for 'cin' executable, and some indirectly for
libav* libraries. So, for ffmpeg-support libs you need
additional env variables for letting it use system components.
There are variable (like auto) in
configure.ac
block for many libraries, so default state does not require
unreasonably long string of --with-* and --enable-* configure
arguments.
At least this is my understanding of difference
between --with-something, --enable-something,
--without-something and --disable-something.
