added feature to configure: --with-aztec=[LOC]
where [LOC] is the location where you installed aztec

for example  in debug mode if you installed aztec in $HOME/aztec

CXXFLAGS="-g3 -O0" configure --with-aztec=$HOME/aztec

lifev will be configured to find aztec headers (resp. libs) in $HOME/aztec/include (resp. $HOME/aztec/lib)

happy coding!
