[Cmake] cmake error: identic name for binary and source cmake run after building

[Jan Woetzel]

Hi,
a 'newbie' question about ADD_EXECUTABLE:
When my executable should have the same base name as the source,
the *second* cmake run (after building it) doesn't work.

I am confused because it doesn't even work in the "CMakeExample" Hello 
world example.

My executables should have the same (base) name as the corresponding 
binary,
Refering to the "CMakeExample":
e.g.
   Demo/demo.cxx
should become
   'demo' executable (and not 'helloDemo') under Linux (and maybe 
demo.exe under Windows which I did'nt test yet).

I edited Demo/CMakeLists.txt:
...
#ADD_EXECUTABLE(helloDemo demo demo_b)
ADD_EXECUTABLE(demo demo demo_b)
...
#TARGET_LINK_LIBRARIES(helloDemo Hello)
TARGET_LINK_LIBRARIES(demo Hello)
...


This works for the first cmake; make run, teh binary 'demo' is there and 
works.
But a second cmake run seems to produce wrong dependnecies.

The subsequent make doesn't work either.

i am using "cmake version 1.6" from website binary.

I didn't find a hint in docu or web,
sorry if it's a typical "newbie" problem.

Best regards,
Jan.
