-Subject: [PATCH] Allow to build with OE llvm & clang cross compiled packages
-
-The default llvm and clang cmake packages requires all libraries, headers
-and tools to be present but in case of cross compilation, OE only
-provides target specific libraries and headers and requires native llvm
-or clang tools.
-
-So instead of looking for a complete llvm & clang packages, look for
-libraries and headers which are installed in target sysroot-recipe path.
-
-Also, fix name for clang library lookup.
