There is (old) documentation for starting up a custom-built KDE at=20
http://kdesrc-build.kde.org/documentation/environment.html

The basic idea is to figure out what file is used to startup a login se=
ssion.=20
KDM has an option to let you configure which desktop to login to (usual=
ly read=20
from a directory like /usr/share/apps/kdm/sessions).

If you have an executable file in your home directory called ".xsession=
", KDM=20
should give you an option to login to a "Custom" desktop (where "Custom=
" just=20
means user-defined).

.xsession is a regular shell script, where you can set environment vari=
ables=20
and then run "startkde" to continue startup. I will probably find a way=
 to=20
automatically install an appropriate setup script at some point. :-/

In the meantime, this file is where you would put the environment varia=
ble=20
defines mentioned in the page I listed. Something like:

#!/bin/sh

# Change these to the install prefix for each (if you modified that)
export QTDIR=3D"$HOME/qt4"
export KDEDIRS=3D"$HOME/kde"

# Execute custom-installed KDE programs by default
export PATH=3D"$KDEDIRS/bin:$QTDIR/bin:$PATH"

# Link to custom-installed KDE libraries by default
export LD_LIBRARY_PATH=3D"$KDEDIRS/lib:$QTDIR/lib:$LD_LIBRARY_PATH"

# Tell Qt where to find KDE-installed plugins
export QT_PLUGIN_PATH=3D"$KDEDIRS/lib/kde4/plugins:$QT_PLUGIN_PATH"

# Might be needed if you try to run 'make' from a kdesrc-build build di=
rectory
export PKG_CONFIG_PATH=3D"$KDEDIRS/lib/pkgconfig:$QTDIR/lib/pkgconfig:
$PKG_CONFIG_PATH"

# Act appropriately if LD_LIBRARY_PATH is not already set.
if [ -z $LD_LIBRARY_PATH ]; then
  export LD_LIBRARY_PATH=3D"$KDEDIRS/lib"
else
  export LD_LIBRARY_PATH=3D"$KDEDIRS/lib:$LD_LIBRARY_PATH"
fi

export KDEHOME=3D"${HOME}/.kde4"

# Create it if needed
[ ! -e ~/.kde4 ] && mkdir ~/.kde4

# Add XDG-compliant paths, for the K Menu, installed programs, etc.
# See http://standards.freedesktop.org/basedir-spec/basedir-spec-latest=
.html
export XDG_DATA_DIRS=3D"$KDEDIRS/share/:$XDG_DATA_DIRS"

# Startup the rest of KDE
exec "$KDEDIRS/bin/startkde"

-----------

So, basically you're trying to setup the "environment" to locate the ne=
wly-
installed libraries, programs, etc., and then you run "startkde" to con=
tinue=20
with the rest of the startup sequence.
