How to add libraries path to the ./configure command

[Nancy]

Dear list,

While I install emacs24.2, I met following problem:
configure: error: The following required libraries were not found:
     libjpeg libgif/libungif libtiff
Maybe some development libraries/packages are missing?
If you don't want to link with them give
     --with-jpeg=no --with-gif=no --with-tiff=no

I have libjpeg-dev installed under /home/yurong/opt
export LD_LIBRARY_PATH=/home/yurong/opt/lib
export LD_RUN_PATH=/home/yurong/opt/lib
then emacs ./configure    again, stll cannot find libjpeg

What should I do?
