There is a command 
```
find_package(KDE4 REQUIRED)
```
 in the CMakeLists.txt file from the question [How to make a project of Krusader](https://askubuntu.com/questions/485386/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](https://askubuntu.com/questions/331204/qt-build-in-ubuntu-12-04); I gave it up at that time, but it appears to be a basic matter.) Thanks!
