Makefile.am:3: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:3: The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:3: to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:3: If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:3: its definition is in aclocal's search path.
autoreconf: automake failed with exit status: 1
Error running autogen
Exiting now.
