This means that the php-symfony-dotenv library is now only needed
when using the legacy scripts. This includes the BDD tests which
currently still rely on the PHP utils.
The default location of osm2pgsql and the postgresql module
is decided at compile/installation time and is not necessarily
in the project directory.
With this change it is now possible to have a project directory
that is completely separate from the build directory.
Instead of creating the website wrapper scripts with cmake,
they are now created when --setup-website is called. The
setup of the configuration constants is directly embedded
into the scripts. This means we can get rid of the separate
settings-frontend.php. More importantly however, it means
that it is now possible to set up multiple website directories
from the same build directory.
This adds the notion of a project directory. This is the directory
that holds all necessary files for one specific installation of
Nominatim. Dotenv looks for an .env file in this directory and
adds it to the global environment together with the defaults from
Nominatim's data directory.
Add's symfony's dotenv library as a new dependency.
CONST_BasePath is split into separate configuration variables
for binaries, libraries and data. These variables as well as
the installation path are now set in the executable directly and
no longer configurable via project settings.
This is the first step towards an installable software. The
executables should know per installation where to find their
necessary data to execute. Project configuration needs to be
restricted to settings that really concern the specific Nominatim
installation.
The parameter got lost when switching to website settings.
Given that the use of a fixed parameter is limited,
debugging output can now only be set via the URL parameter.
Just make cmake install a small stub that includes
the settings from the build directory and then the
script from the source directory. Remove executable
rights from php files in utils/ so that they cannot
be accidentally executed.
