#72468: libplacebo broken by wrong syntax in meson.build, unnecessarily so
--------------------------+------------------------
 Reporter:  barracuda156  |      Owner:  (none)
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.10.7
 Keywords:                |       Port:  libplacebo
--------------------------+------------------------
 `libplacebo` failed at linking due to meson passing `''` to the linker.
 That was happening because of incorrect syntax: instead of just not
 passing unneeded flag, it passed those double quotes, which linker
 understood as a filename. This is a quick fix: https://github.com/macos-
 powerpc/powerpc-
 ports/blob/0e1710ce6734a2f8e6608656e89a20f0db55739d/devel/libplacebo/files
 /patch-fix-silly-bug.diff
 (Of course, it should not be merged in this form, because some systems
 where `has_setclock` is true presumably need the flag added.)

 It is desirable to have fixed, because not having `libplacebo` was a
 stopper to have modern `mpv`.
