Cannot edit CMakeLists.txt

[Dimitrios Eftaxiopoulos]

Hello,
I have created a simple C++ sample "Hello world" project which works fine. When 
I edit the CMakeLists.txt file, bring it back to its original form eventually 
and save it, i.e. no changes are done to the CMakeLists.txt file, I get the 
error

/cppproj/build> make
CMake Error: Error in cmake code at /cppproj/CMakeLists.txt:1:
Parse error.  Expected a command name, got unquoted argument with text 
"project".
-- Configuring incomplete, errors occurred!
make: *** [cmake_check_build_system] Error 1
*** Failed ***

when I launch the configuration.

I use a fresh install of kdevelop 4.1, but the same happened with 4.0.1.

Regards
Dimitris
