[CMake] EXECUTE_PROCESS - I can't copy files on Windows

	Thanks Filipe. Much more "cleaner" way.
	I was using only the Mastering CMake book, but I'm observing a lot of
improvements from 2.2 to 2.4 version. Now I'll always look at CMake help.

	Well, unfortunaly, no. I tried a simpler command, that copies only one
file that is located in actual directory to my test directory.
	My structure is that:
	
	C:\...\mylib
	C:\...\mylib\mytest

	I tried:

      EXECUTE_PROCESS(${CMAKE_COMMAND} -E copy "teste.txt" "mytest"
		RESULT_VARIABLE resultado
		ERROR_VARIABLE erro )

      MESSAGE ("resultado: " ${resultado})
      MESSAGE ("erro: " ${erro})

	(I have the teste.txt file inside mylib dir)
	I got the following error:

C:\Documents and Settings\vasconcv\work\conta\mylib>cmake .
-- Who am I? Windows
--- Copying TEST files arguments needed to performe unit tests...

Current CMake stack: Z:/Qgar/mylib/mytest/CMakeLists.txt
resultado:

	When I tried "by hand" in command line:

	cmake -E copy teste.txt mytest

	It worked fine.
	Thanks a lot and I hope to get a solution. It seems not to be a big
problem, is it?
