The setup relies on the project configuration which we want to
explicitly set up in later steps. Therefore proxy setup needs to
be done explicitly as well. There is the added bonus that the
setup is done only for the utils which try to call outside.
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.
Instead add it as a configurable path with the one from
the source directory as the default.
Also reinstates that settings/defaults.php is installed as
settings/settings.php.
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.
Executables (including websites) need to be installed in the
build directory, so that they can find the right settings.php.
settings now defines build and source dir.
