+weston-1.5.0/configure.ac: make lcms explicitly configurable
+
+The lcms package is outside of openembedded-core, so make it
+explicitly configurable. Make it deterministic, so that if lcms
+dependencies are missing, autoconf throws a fatal error. Follow
+upstream style to make it more likely to be merged.
+
+Upstream-Status: Pending
