+Subject: [PATCH] opencv: resolve missing opencv data dir in yocto build
+
+When Yocto build is performed, opencv searches for data dir using simple
+'test' command, this fails because pkg-config provides an absolute
+path on the target which needs to be prepended by PKG_CONFIG_SYSROOT_DIR
+in order for the 'test' utility to pick up the absolute path.
+
+Upstream-Status: Inappropriate [OE-specific]
