4Subject: [PATCH 4/4] opencv: resolve missing opencv data dir in yocto build
5
6When Yocto build is performed, opencv searches for data dir using simple
7'test' command, this fails because pkg-config provides an absolute
8path on the target which needs to be prepended by PKG_CONFIG_SYSROOT_DIR
9in order for the 'test' utility to pick up the absolute path.
