Cmake very simple set failure

I trying to start using cmake with the simplest helloworld example, in ubuntu 12.04, cmake 2.8.7. First I tried the one from:

http://www.elpauer.org/stuff/learning_cmake.pdf

project( helloworld )
set( SRCFILES helloWorld.cpp )
add_executable( helloWorld ${SRCFILES} )

I have only a source file called "helloWorld.cpp" by the side of the CMakeLists.txt. I created a directory called "configure", went inside and called "cmake ..". I get the following:

-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
CMake Error at CMakeLists.txt:3 (add_executable):
  add_executable called with incorrect number of arguments


-- Configuring incomplete, errors occurred!

Trying to figure out what wrong I got all the following changes:

project( helloworld )
set( SRCFILES helloWorld.cpp )
message ( "src ${SRCFILES}" )
set(x helloWorld.cpp)
set(y 2)
message(${x}${y})
message(${x}${y})
message(${SRCFILES})

add_executable( helloWorld ${SRCFILES} )
add_executable( helloWorld ${x} )
add_executable( helloWorld helloWorld.cpp )

The results again finish with:

...
-- Detecting CXX compiler ABI info - done
src 
helloWorld.cpp2
helloWorld.cpp2
CMake Error at CMakeLists.txt:8 (message):
  message called with incorrect number of arguments


CMake Error at CMakeLists.txt:10 (add_executable):
  add_executable called with incorrect number of arguments


CMake Error at CMakeLists.txt:11 (add_executable):
  add_executable called with incorrect number of arguments


CMake Error at CMakeLists.txt:12 (add_executable):
  add_executable called with incorrect number of arguments


-- Configuring incomplete, errors occurred!

Finally, the trivial

project( helloworld )
add_executable( helloWorld helloWorld.cpp )

Fails with:

...
-- Detecting CXX compiler ABI info - done
CMake Error at CMakeLists.txt:2 (add_executable):
  add_executable called with incorrect number of arguments


-- Configuring incomplete, errors occurred!

Before each trial I remove all files within compile. I just can't figure out what is missing and why the variable is set.. not set... useless?

Thank you very much for your help.

You probably copied the same corrupted text from a webpage as I did. There must be some hidden character in the text. Re-writing the line manually solved it also for me.
