autogen_rel_py3.sh       ==>  generates library for use from within python and C++
autogen_rel_py3_noqt.sh  ==>  generates library for use from within python and C++ (remove Qt4 dependency if xml not required)
autogen_rel_noqt.sh   ==>  generates library for building a mex file (remove Qt4 dependence as matlab requires Qt5)
autogen_rel.sh        ==>  normal c++ release

Libraries are only made available when the appropriate is enabld

1) Modify autogen.sh according to above
2) 'source autogen.sh'
3) 'make'
4) 'make install'  This installs cafe headers/libraries to the directories 
   specified by --prefix/--libdir in the above
