Original commit message from CVS:
- my mistake... mpeg2dec libs does not depend on X11 libraries
(vo library distributed with mpeg2dec depends on X11 libs).
Add configure option so user can specify where mpeg2dec library
is installed. This way we do not guess where is mpeg2dec.
If it is not in standard location (prefix==/usr), then leave it
to the user.
Changes inspired by AM_PATH_LIBMIKMOD.
Original commit message from CVS:
- GST_CHECK_MPEG2DEC macro - checks for mpeg2dec in /usr/lib.
If not found then checks for mpeg2dec in /usr/X11R6/lib.
This macro is needed because mpeg2dec depends on X11R6 libraries
and as FHS states, it should be placed in /usr/X11R6 tree but
some distros do not care and put mpeg2dec into /usr/lib.
It depends on CHECK_LIBHEADER macro.
Original commit message from CVS:
- CHECK_LIBHEADER macro, which is based on GST_CHECK_LIBHEADER
the main difference between them is that you can specify cpp flags with
CHECK_LIBHEADER
