+Subject: [PATCH] build(lib): Add extra repositories for system includes
+
+Toolchains such as aarch64-none-elf, aarch64-none-linux-gnu and
+aarch64-linux-gnu include assert.h and limits.h in a directory that is
+part of their search path.  This is not the case when compiling with
+Yocto where aarch64-poky-linux places those files in the sysroot
+directory of the component being compiled.
+
+Since the sysroot directory of the component is not part of the cmake
+search path, compiling the RMM in Yocto fails.  This patch fixes the
+problem by expanding the search path when needed, allowing the RMM to be
+compiled in Yocto.
+
