g++ cannot find shared library

I apologize that this is redundant, but none of the answers available seem to be able to solve my problem. I am attempting to compile an executable using a shared object library. The shared object library is called libsession.so and is found in the same directory that I am compiling the executable. To compile and link, I use the following command

g++ test_main.cpp -o program -std=c++11 -I ../src/base -L. -lsession

Unforutanely, I get the cannot find -lsession error when linking. If I change the command to directly reference the shared library as follows

g++ test_main.cpp -o program -std=c++11 -I ../src/base libsession.so

then the executable compiles/links and all is well. Does anyone have any thoughts as to what I may be doing wrong?

Actually it follows specific naming convention like library name should be preceded by lib. so if you change library name to libsession.so it will work.

The only difference between using an '-l' option and specifying a file name is that '-l' surrounds library with 'lib' and `.a' and searches several directories.
