[Cin] opencv build trim

[Andrew Randrianasulu]

on topic of opencv I instalked opencv 4.5.5 on termux and tried to build
cingg plugins against this.

most plugins worked with hack - but for some reason final link faild to add
opencv libs (no pkgconfig for them, it seems?) and so resulted plugins
aborted cin on load.


hack:

$ git diff thirdparty/Makefile plugins/Makefile
diff --git a/cinelerra-5.1/plugins/Makefile b/cinelerra-5.1/plugins/Makefile
index e6718432..cb3a10e8 100644
--- a/cinelerra-5.1/plugins/Makefile
+++ b/cinelerra-5.1/plugins/Makefile
@@ -8,7 +8,8 @@ endif
 ifneq ($(WANT_OPENCV), no)
 want_var:=$(WANT_OPENCV)
 include $(TOPDIR)/opencv_build
-OPENCV_OBJS := findobj flowobj gaborobj moveobj stylizeobj puzzleobj
+#OPENCV_OBJS := findobj flowobj gaborobj moveobj stylizeobj puzzleobj
+OPENCV_OBJS := flowobj gaborobj moveobj stylizeobj findobj
 $(OPENCV_OBJS): opencv
 endif
 ifneq ($(WANT_CUDA), no)


err, not all changes...

puzzleobj failed to build anyway, so I commented it out.

may be on more standart Linux dynamuc/system build with this hack still
will work (produce usable plugins?)
