I usually build my library ./configure && make && sudo make install. However the Travis docs discourage using sudo http://docs.travis-ci.com/user/workers/container-based-infrastructure/
So I changed the build command to ./configure --prefix=$HOME && make && make install. This worked, however at the next step (building a Python extension) I got an error
/usr/bin/ld: cannot find -lprimesieve
Any ideas? Do I need to add $HOME/lib to some environment variables, because I changed prefix?
- My travis config https://github.com/hickford/primesieve-python/blob/travis-ci/.travis.yml

Try setting set LD_LIBRARY_PATH which is like PATH for libraries. For example:
LD_LIBRARY_PATH= $HOME/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
More detailed information about library path variables is here.
Environment variables that specifically influence how the configure script passes arguments to compilation are LIBS and LD_FLAGS. bash ./configure --help mentions these.
And as you mention in the comments LIBRARY_PATH also needs to be set. See LD_LIBRARY_PATH vs LIBRARY_PATH for an explanation of the difference.
