+# This file sets up a CMakeCache for the simple VE build.
+#
+# VE is a CPU with vector engine.  But it is a connected to a host CPU as
+# an accelerator.  So, we compile programs for VE on a host using clang/llvm
+# as a cross compiler.  Therefore, the purpose of this cache file is to
+# compile clang/llvm supporting both targets.
+#
+# Configure:
+#   cmake -G Ninja -DCMAKE_BUILD_TYPE=Release
