Hello :)
Original (old) version of FindGStreamer.cmake can set only one directory
and set it to
/usr/include/gstreamer-1.0;
New version of FindGStreamer.cmake (without PC_) set it to this:
GSTREAMER_INCLUDE_DIRS:INTERNAL=/usr/include/gstreamer-1.0;
*/usr/lib64/gstreamer-1.0/include*
;/usr/include/glib-2.0;/usr/lib64/glib-2.0/include
in the new 1.5.2 GStreamer there are some headers in the lib64 directory
(don't know why... I can fix it by creating two symbolic links etc. ;)
*# cd /usr/lib64/gstreamer-1.0*
*# ls -R include*
*include/:gstinclude/gst:gl gstconfig.hinclude/gst/gl:gstglconfig.h*
PS
gstreamer-1.0.pc looks like
prefix=/usr
exec_prefix=${prefix}
libdir=/usr/lib64
includedir=${prefix}/include/gstreamer-1.0
toolsdir=${exec_prefix}/bin
pluginsdir=/usr/lib64/gstreamer-1.0
datarootdir=${prefix}/share
datadir=${datarootdir}
girdir=${datadir}/gir-1.0
completionsdir=${datarootdir}/bash-completion/completions
helpersdir=${datarootdir}/bash-completion/helpers
typelibdir=${libdir}/girepository-1.0
