Makefile.configmake

# LGPLv2+

# Retrieve values of the variables through 'configure' followed by
# 'make', not directly through 'configure', so that a user who
# sets some of these variables consistently on the 'make' command
# line gets correct results.
#
# One advantage of this approach, compared to the classical
# approach of adding -DLIBDIR=\"$(libdir)\" etc. to AM_CPPFLAGS,
# is that it protects against the use of undefined variables.
# If, say, $(libdir) is not set in the Makefile, LIBDIR is not
# defined by this module, and code using LIBDIR gives a
# compilation error.
#
# Another advantage is that 'make' output is shorter.
#
# Listed in the same order as the GNU makefile conventions.
# The Automake-defined pkg* macros are appended, in the order
# listed in the Automake 1.10a+ documentation.
