How to build from source when there's no configure file

Question

Usually I start with ./configure, but there's no configure file supplied. These are the directory contents:

autogen.sh      configure.ac  GNUmakefile.am  Makefile.shared  Source  WebKitLibraries  wscript
CMakeLists.txt  Examples      Makefile        ManualTests      Tools   WebKit.pro

How do I build this? Am I supposed to run autogen.sh? I tried that, and this was the result:

autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal -I Source/autotools 
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --install --copy
libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, `Source/autotools'.
libtoolize: copying file `Source/autotools/config.guess'
libtoolize: copying file `Source/autotools/config.sub'
libtoolize: copying file `Source/autotools/install-sh'

libtoolize: copying file `Source/autotools/lt~obsolete.m4'
libtoolize: Consider adding `-I Source/autotools' to ACLOCAL_AMFLAGS in Makefile.am.

GNUmakefile.am:235:   `Tools/GNUmakefile.am' included from here
GNUmakefile.am: installing `Source/autotools/depcomp'
autoreconf: automake failed with exit status: 1

What happened?

It looks like this project uses cmake; try:

 mkdir build
 cd build
 cmake ..
