# The ExternalProject builds of Tutorial Step5 cannot be built
# correctly 2nd and later times in an in-source build...
# (because the CMakeCache.txt from the real in-source build of

# the "source directory copy" step... but it still refers to
# its original path which yields a configure error.) So:
