(In reply to Alfredo Pons Menargues from comment #0)
The failure is:

error: conflicting declaration ‘typedef void* GLsync’

The problem is that gstreamer sees the original gl2ext.h file from
rpi-userland
(rpi-userland-093b30bbc2fd083d68cc3ee07e6e555c6e592d11/interface/khronos/include/GLES2/gl2ext.h)
without the additional GLint64, GLuint64 and GLsync typedef definitions but
checks for existance and if not found enables its own versions in
gstgl_compat.h,
incompatible with the later ones used from Qt (qopengles2ext.h).
An RFC patch suggested, see:
https://patchwork.ozlabs.org/project/buildroot/patch/20210510195352.13205-1-ps.report@gmx.net/
Only compile tested (yet)...
