rpicamsrc: lookup for bcm_host and friends using dependency mechanics
I'm cross-compiling GStreamer 1.18 for RPi board and found there are several components that depend on
bcm_host library and friends. However various components detect libraries in inconsistent ways.
Please use the same
dependency mechanics for
rpicamsrc to detect
In this case it's only enough to add
$sys_root/opt/vc/lib/pkgconfig additional path to
pkg_config_libdir in order to make all
bcm_hiost dependent parts to build.
