[CMake] Visual Studio 2010 generator and custom command

[elizabeta petreska]

Hi,

I asked this question some time ago in the mailing list. Unfortunately, I
did not try to resolve this issue since then, so I am trying again. :)

I am using Visual Studio 2010 generator and cmake 2.8.2.

Why the following custom command is runing all the time, although the input
dependency ( myfile.txt ) is not changed ? With Visual Studio 2005 it is
working ok.

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(quick_test)

ADD_CUSTOM_COMMAND(
 OUTPUT "${PROJECT_BINARY_DIR}/$(ConfigurationName)/generated.txt"
 COMMAND ${CMAKE_COMMAND} -E copy
  "${PROJECT_SOURCE_DIR}/myfile.txt"
  "${PROJECT_BINARY_DIR}/$(ConfigurationName)/generated.txt"
 DEPENDS "${PROJECT_SOURCE_DIR}/myfile.txt"
 )
ADD_CUSTOM_TARGET(${PROJECT_NAME} DEPENDS
"${PROJECT_BINARY_DIR}/$(ConfigurationName)/generated.txt")
