#
# Setup a number of parameters.  Until we get 6bed4 standardised,
# these are preliminary values that MUST NOT be assumed static.
#
# This is why CMake will present a warning, but it will still
# go ahead with the values.  They can be changed at will using
# any tool that interacts with the CMakeCache.txt file or that
# overrides the settings at build time.
#
# Please beware that the values contain the information in a
# number of different forms.  In a perfect world, we would
# derive values from one another.  In a portable world, for
# now at least, we resort to letting you maintain consistency.
