It works for *building* libodb-mysql but not for *installing* it since
an installed library should not reference a non-installed one.

Sorry, I made a mistake in the command. Instead of ~/ODB2.1/libodb-2.1.0
in CPPFLAGS and LDFLAGS it should have been ~/ODB2.1/local:

./configure --prefix=/home/ststrou/ODB2.1/local CPPFLAGS=-I/home/ststrou/ODB2.1/local/include LDFLAGS=-L/home/ststrou/ODB2.1/local/lib

Backslashes are used to break a long command into multiple lines,
for better readability.

Modern linkers are quite tricky in this regard and may require a
shared library to be loadable just to link it to another library.
See the -rpath-link ld option for details. So it is safer to just
add /home/ststrou/ODB2.1/local/lib to LD_LIBRARY_PATH before
building.

Note also that it is LD_LIBRARY_PATH, not LD_LIBRARY_FLAGS.
