On techbase.kde.org there are some detailed instructions on how to set up a 
KDE development environment. I have such a setup, including the additions 
to .bashrc which make life easier.

You certainly dont need to edit digikam's CMakeLists.txt if your setup is 
correct...Have you the required version (> 2.4.5) of CMake installed?
CMake comes with a small KDE module which in turn locates the main KDE CMake 
modules that comes with kdelibs (FindKDE4internal.cmake)
Have you set the KDEDIR variables?
With the bashrc additions mentioned above, I have always set:

export KDEDIR=/usr/kde/4.0
export PATH=$KDEDIR/bin:$PATH
export LD_LIBRARY_PATH=$KDEDIR/lib:$LD_LIBRARY_PATH
export QT_PLUGIN_PATH=$KDEDIR/lib/kde4/plugins
export KDEDIRS=$KDEDIR

export PKG_CONFIG_PATH=$KDEDIR/lib/pkgconfig:$PKG_CONFIG_PATH

# User
export KDEHOME=$HOME/.kde4
export KDETMP=/tmp/$USER-kde4
mkdir -p $KDETMP
export KDEVARTMP=/var/tmp/$USER-kde4

# build and src folders
# you might want to change these!
export KDE_BUILD=$HOME/freshmeat/multimedia/kde4/build
export KDE_SRC=$HOME/freshmeat/multimedia/kde4/src
