Subject: [PATCH] Query pkg-config for libplacebo library location

The location of libplacebo could vary between systems, as it's
fast-changing library with very dynamic API. This could force having
various versions on the system for different applications. Use
pkg-config to provide location of targeted libplacebo version, by
providing custom PKG_CONFIG_PATH environmet variable.
