#---------------------------------------------------------------------
-# Searching the system for packages presents something of a dilemma -
-# in most situations it is Very Bad for a BRL-CAD build to be using
-# older versions of libraries in install directories as search results.
-# Generally, the desired behavior is to ignore whatever libraries are
-# in the install directories, and only use external library results if
-# they are something already found on the system due to non-BRL-CAD
-# installation (source compile, package managers, etc.). Unfortunately,
-# CMake's standard behavior is to add CMAKE_INSTALL_PREFIX to the search
-# path once defined, resulting in (for us) the unexpected behavior of
-# returning old installed libraries when CMake is re-run in a directory.
-#
-# To work around this, there are two possible approaches. One,
-# identified by Maik Beckmann, operates on CMAKE_SYSTEM_PREFIX_PATH:
-#
-# http://www.cmake.org/pipermail/cmake/2010-October/040292.html
-#
-# The other, pointed out by Michael Hertling, uses the
-# CMake_[SYSTEM_]IGNORE_PATH variables.
-#
-# http://www.cmake.org/pipermail/cmake/2011-May/044503.html
-#
-# BRL-CAD initially operated on CMAKE_SYSTEM_PREFIX_PATH, but has
-# switched to using the *_IGNORE_PATH variables. This requires
-# CMake 2.8.3 or later.
-#
-# The complication with ignoring install paths is if we are
-# installing to a "legitimate" system search path - i.e. our
-# CMAKE_INSTALL_PREFIX value is standard enough that it is a legitimate
-# search target for find_package. In this case, we can't exclude
-# accidental hits on our libraries without also excluding legitimate
-# find_package results. So the net results are:
-#
-# 1. If you are planning to install to a system directory (typically
-# a bad idea but the settings are legal) clean out the old system
-# first or accept that the old libraries will be found and used.
-#
-# 2. For more custom paths, the logic below will avoid the value
-# of CMAKE_INSTALL_PREFIX in find_package searches
-#
-# (Note: CMAKE_INSTALL_PREFIX must be checked in the case where someone
-# sets it on the command line prior to CMake being run. BRLCAD_PREFIX
-# preserves the CMAKE_INSTALL_PREFIX setting from the previous CMake run.
-# CMAKE_INSTALL_PREFIX does not seem to be immediately set in this context
-# when CMake is re-run unless specified explicitly on the command line.
-# To ensure the previous (and internally set) CMAKE_INSTALL_PREFIX value
-# is available, BRLCAD_PREFIX is used to store the value in the cache.)
