# ---------------------------

#
#
# 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 will be set to the release value, and
# basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND.
# If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will
# take the debug value, and basename_LIBRARY_RELEASE will be set to
# basename_LIBRARY_RELEASE-NOTFOUND.
#
# 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 value, or the debug value if the release one is
# not set.

# This macro was adapted from the FindQt4 CMake module and is maintained by Will
# Dicharry <wdicharry@stellarscience.com>.
