[CMake] Executables with the same name as libs

[Ken Martin]

After some more brainstorming it seems there is a better way to handle this.
Basically targets must be unique, but you can change the name of the output
produced for executable targets.  This results in something like


# and two targets in the same dir with the same name
ADD_LIBRARY(mytest2 ../Lib1/libc1.c)

ADD_EXECUTABLE(mytest2_exe conly.c)
SET_TARGET_PROPERTIES(mytest2_exe PROPERTIES OUTPUT_NAME mytest2)
TARGET_LINK_LIBRARIES(mytest2_exe mytest2)


This snippet is from the SameName test I just added into CMake (not enabled
yet). The two targets have different target names but by setting the
OUTPUT_NAME property on mytest2_exe we can make the executable produced be
called just mytest2. I have committed these changes for Makefiles, VS7 and
untested in VS6, although there are probably some gotchas still in there.
This seems much cleaner.

Thanks
