spa: libcamera: plugin does not build with the latest libcamera
Upstream commit 6a31a8d8e2742990f3b3a3dbf5157a9e1cb835ea renamed
framebuffer.h. This causes
libcamera_wrapper.cpp to fail to compile. Unfortunately there doesn't seem to be a reliable way of checking the libcamera version, so possibly the presence of the newer header file could be checked.
