Ubuntu – Libjpeg not found

I have an binary program to run on ubuntu. It has shared object dependency. pmvs is the name of the program

   $ ldd pmvs
        linux-vdso.so.1 =>  (0x00007fff043c3000)

        libjpeg.so.62 => not found
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa14d747000)
        liblapack.so.3 => not found
        libgsl.so.0 => not found
        libgslcblas.so.0 => not found
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fa14d449000)

        libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007fa14c347000)

It apparently cannot find libjpeg.so. However I am sure that it exist and is at : "/usr/lib/x86_64-linux-gnu/libjpeg.so". How to I set the linker path to include that location.

I have ubuntu 12.04
