Makefile

# Thin wrapper around CMake so the usual './configure && make && make install'
# dance works. Every target here just shells out to cmake -- there is nothing
# else going on.
#
# If you run 'make' before ./configure, we auto-configure with default flags.
# Customise the build by running ./configure yourself with the options
# printed by './configure --help'.
