# Generic library install file
#
# This file assumes the following variables are defined:
#   LIBNAME       -- the name of the library
#   HEADERFILES   -- header files to be installed
#   LIBFILES      -- library files to be installed
#
# There must be a file named Version, in which the first word of the first
# line must be the version number, such as 0.5.17
#
# Two modes of the install are supported:
#   INSTALLMODE=native        install right into $(PREFIX)/{lib,include}
#   INSTALLMODE=separate      (default) create a separate directory
#
# In case you wouldn't like include files to be placed in a separate
# directory, use NOINCLUDEDUR variable:
#   NOINCLUDEDIR  -- set to 'yes' if the library doesn't need
#                    a separate directory for include files
#
# In order to prepare a package, DESTDIR can be specified.  In this case,
# all other directories are relative to DESTDIR. Mode must be native in
# order this to work.
