+# CAUTION: In heterogeneous environments where different cross compilers are
+# used for different CPUs, particularly if from different vendors, it is likely

+# In general, options in this file can only be used in cases where all CPUs use a
+# compiler from the same vendor and/or are all GCC based such that they accept similar 
+# command line options.
+#
+# This file can alternatively be named as "arch_build_${TARGETSYSTEM}.cmake" 
+# where ${TARGETSYSTEM} represents the system type, matching the toolchain.
+#
+# These example options assume a GCC-style toolchain is used for cross compilation,
+# and uses the same warning options that are applied at the mission level.
