When you have problems like this, you need to take it in small
steps.
o What shell are you using? Yagnesh's recommendation assumes
that you are running bash as your shell (presumably on some
Linux/Unix system). Is this assumption correct?
o Assuming you are using bash, there are two relevant initialization
files: a login shell sources $HOME/.profile and any shell (be it a login
shell or one that is started as a descendant of your login shell) sources
$HOME/.bashrc.
o Adding
export FOO=bar
to such an initialization file causes the variable FOO to be defined (with value "bar")
and to be exported (i.e. it is available in the environment of *any* subprocess of
this shell).
o So log out and log back in[fn:2], start a shell and at the prompt say
echo $FOO
Does it say "bar"? If not, don't go any further: the problem has nothing to do with
emacs (note that this is the first time I mention emacs).
o If this part is OK, start emacs *from this shell*: it should inherit the variable.
You can check by evaluating this form:
(getenv "FOO")
Then the variable will also be available to any subprocesses started by emacs.
o In particular, if you define BIBINPUTS as Yagnesh suggests, then the bibtex invoked
by the latex exporter under emacs will find the bib file where you told it.
o What can go wrong? The usual problem is that you use some graphical
desktop environment and start emacs by clicking on some icon. Then
the emacs process does not have a bash shell as its parent, so it does
not inherit the exported variables. Try starting emacs from a bash
command line.[fn:2]

Footnotes:
[fn:1] If you define it in .bashrc, you shouldn't have to log out and log
back in: just start a new bash shell.
[fn:2] I prefer defining variables in my .profile and I have arranged
for my .profile to be sourced by the appropriate initialization
file of my graphical desktop environment, so I get it whether I
log in at the console or through the graphical login. That
way *every* process, no matter how it is started, has the
variables available to it. I use .bashrc only for aliases (which
I use very rarely, so most of the time I don't have a .bashrc
file at all).
