so the following works:
suppose you have checked out
primesieve/
and
primcount/

cd primesieve
cmake . -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=OFF
make && sudo make install

cd ../primcount
cmake . -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=OFF -DBUILD_LIBPRIMESIEVE=OFF
make # this only builds primecount
sudo make install
sudo ldconfig # cause cmake is a bit silly here
cd
primecount 1000000000 # test - almost instant
50847534
