SDDM uses CMake to configure and build the project.
mkdir buildcd build && cmake ..make.make install.CMake accepts a number of standard and extra arguments:
By default, a debug build is created. To build for production, use
cmake -DCMAKE_BUILD_TYPE=Release.
To see all the possible arguments, run cmake -L ...
For documentation on standard CMake variables, see:
http://www.cmake.org/cmake/help/v3.0/manual/cmake-variables.7.html
By default, SDDM runs as its own user. An sddm user needs to be created, with
its home set to /var/lib/sddm by default.
SDDM depends on PAM for authorization and XCB to communicate with the X server.
Apart from other things, it also depends on Qt for the user interface and event
loop management.
SDDM can optionally make use of logind (the systemd login manager API), or
ConsoleKit2, or upower to enable support for suspend, hibernate etc.
In order to build the man pages, you will need rst2man installed. It is
provided by the python docutils package
Note that SDDM makes use of C++11 features for a modern and clean codebase, therefore it needs a recent version of GCC to compile (4.7 at least).
