It's a bit of a chicken and egg problem, otherwise. Well, of course one
can use kdesrc-build uninstalled, but this way an automated build host
can just start with "./kdesrc-build/kdesrc-build kdesrc-build" to ensure
it's up-to-date :-)
use the SUBDIR parameters for kde4_create_handbook, so it installs in the proper place
remove the comment related to the issue, and enable the doc subdir
To avoid kdesrc-build build errors, it's probably easiest just to
have a shell CMakeLists.txt which CMake can process and do nothing
with.
At some point it will be used to make the docs build, but right
now the docs install to the wrong directory (as if the name of
the project was "doc" instead of kdesrc-build), so installation
is disabled.
