There is a command

find_package(KDE4 REQUIRED)

in the CMakeLists.txt file from the question How to make a project of Krusader. My attempts to build the project in the Qt Creator result in a message

CMake Error at /usr/share/cmake-2.8/Modules/FindKDE4.cmake:98 (MESSAGE):

  ERROR: cmake/modules/FindKDE4Internal.cmake not found in

  /home/me_user/.kde/share/apps;/usr/share/kde4/apps

Call Stack (most recent call first):

  CMakeLists.txt:8 (find_package)

What particular should I install into the Ubuntu 12.04 to satisfy the line 'find_package(KDE4 REQUIRED)'? (I asked about the same problem in Qt build in Ubuntu 12.04; I gave it up at that time, but it appears to be a basic matter.) Thanks!
