websockets are installed to /usr/local, CMAKE_INSTALL_PREFIX is ignored

[andsok75]

cmake installs websockets into /usr/local, even if CMAKE_INSTALL_PREFIX points to a different directory. For instance, I have

CMAKE_INSTALL_PREFIX /opt/acfr

but I still get the following:

/usr/local/lib/websocketd
/usr/local/lib/websocketd/snark-image-frames
/usr/local/lib/systemd/system/snark-webframes.service
/usr/local/lib/systemd/system/tcp-ws-server.service
/usr/local/lib/systemd/system/websocketd.service
