This is preferable +# to the -DVAR=value switches because it insulates the +# users from changes we may make in this script. +# It also offers a little more flexibility than setting +# the CMAKE_*_PATH since we can target specific components. +# However, the default CMake behavior will search system paths +# before anything else. This is problematic in the cases +# where you have an older (stable) version installed, but +# are trying to build a newer version. +# CMake doesn't offer a nice way to globally control this behavior +# so we have to do a nasty "double FIND_" in this module. +# The first FIND disables the CMAKE_ search paths and only checks +# the environmental paths. +# If nothing is found, then the second find will search the +# standard install paths. +# Explicit -DVAR=value arguments should still be able to override everything. +# Note: We have added an additional check for ${CMAKE_PREFIX_PATH}. +# This is not an official CMake variable, but one we are proposing be +# added to CMake.
