Does sqlite have to be installed or can it be imported in code

I want to write a small program that stores simple data. However the computer that this program will operate on is very secure. Installing anything on this system is out of the question. I was wondering if sqlite can be added as a library to a C application or any language not necessarily C. I assumed C/C++ would be easiest being compiled. I know it might not make much since because how can I run my application on this system but not install sqlite but this is the restraints that I am in. Any advice or resources will be very greatful.
