CMAKE_INSTALL_PREFIX is supposed to be used to set an install prefix
of e.g. /usr or /usr/local. Because we need to install files to /etc,
we had been requiring CMAKE_INSTALL_PREFIX=/ and installing using
relative paths.
The best practice method is to install to /etc using absolute paths,
and then allow CMAKE_INSTALL_PREFIX to set where the final binaries
actually go. Now that it actually has some meaning, the systemd
service is generated to incorporate that path.
Those wishing to use "make install" to install laminar to a subdir
should use "make DESTDIR=path/to/subdir install" and NOT modify
CMAKE_INSTALL_PREFIX.
Documentation and packaging scripts updated accordingly.
This helps avoid confusion with the 'docker' directory. Also restore
the debian9 scripts which may be useful for a while longer, update
the names of the scripts and update the README accordingly.
Now that capnp/kj provides http and websocket functions, replace
the excellent websocketpp library with the kj functions. This
removes a dependency and allows for more consistent idiomatic
code. Thanks websocketpp, it was great to have you along!
This should enable parts of the refactor described in #49
