cmake error on Ubuntu 9.10: several NOTFOUND variables

[GoogleCodeExporter]

Downloaded and extracted violetland-v0.2.8.

first I did:
sudo apt-get install cmake
cd violetland-v0.2.8

Then, as per README_EN.TXT, did the following:
mkdir build
cd build
cmake ..

This results in:
CMake Error: The following variables are used in this project, but they are
set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake
files:
SDLIMAGE_INCLUDE_DIR
   used as include directory in directory /home/kostmo/violetland-v0.2.8
SDLIMAGE_LIBRARY
    linked by target "violetland" in directory /home/kostmo/violetland-v0.2.8
SDLMIXER_INCLUDE_DIR
   used as include directory in directory /home/kostmo/violetland-v0.2.8
SDLMIXER_LIBRARY

   used as include directory in directory /home/kostmo/violetland-v0.2.8

-- Configuring incomplete, errors occurred!

My machine is 64-bit, btw.

Update:
It worked after I did the following:

sudo apt-get install libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev

• Changed state: Invalid

I think it would be helpful to add the requisite apt-get line to README_EN.TXT
(section 4).

That line is:
sudo apt-get install cmake libsdl-ttf2.0-dev libsdl-mixer1.2-dev 
libsdl-image1.2-dev

This would eliminate the trial-and-error aspect of Ubuntu compilation.
