# 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:
