+# select_library_configurations( basename )
+#
+# This macro takes a library base name as an argument, and will choose good
+# values for basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and
+# basename_LIBRARY_RELEASE depending on what has been found and set.  If only
+# basename_LIBRARY_RELEASE is defined, basename_LIBRARY, basename_LIBRARY_DEBUG,
+# and basename_LIBRARY_RELEASE will be set to the release value.  If only
+# basename_LIBRARY_DEBUG is defined, then basename_LIBRARY,
+# basename_LIBRARY_DEBUG and basename_LIBRARY_RELEASE will take the debug value.  
+#
+# If the generator supports configuration types, then basename_LIBRARY and
+# basename_LIBRARIES will be set with debug and optimized flags specifying the
+# library to be used for the given configuration.  If no build type has been set
+# or the generator in use does not support configuration types, then
+# basename_LIBRARY and basename_LIBRARIES will take only the release values.
+
+# This macro was adapted from the FindQt4 CMake module and is maintained by Will
+# Dicharry <wdicharry@stellarscience.com>.
+
+# Utility macro to check if one variable exists while another doesn't, and set
+# one that doesn't exist to the one that exists.
