[Insight-developers] SimpleITK - CMake question (The Saga of Eggs on Windows…)

Hello,

Thanks for all the help I have gotten on this issue. It truly has been extremely difficult getting this egg distribution package working on window!

On my virtual machines I am able to create eggs!!! So we are almost there!!

http://www.cdash.org/CDash/buildSummary.php?buildid=1563093

Unfortunately, on the mayos dashboard machines were are still getting some cmake related issues:

http://www.cdash.org/CDash/buildSummary.php?buildid=1561908
http://www.cdash.org/CDash/buildSummary.php?buildid=1562590

These are running cmake 2.8.4, where as I am running 2.8.5. I am suspicious this may be related to the cmake version. I am running windows 7, and I am not certain which os version is being run at Mayo.

This is the error:
http://www.cdash.org/CDash/viewBuildError.php?buildid=1562590

Error copying file "/.../SimpleITK/Wrapping/PythonPackage/ez_setup.py" to "D:/T/vs10/SimpleITK-build/SimpleITK-build/Wrapping/PythonPackage/".
  
C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(113,5): error MSB3073: The command ""C:\Program Files\CMake 2.8\bin\cmake.exe" -E copy /.../SimpleITK/Wrapping/PythonPackage/ez_setup.py D:/T/vs10/SimpleITK-build/SimpleITK-build/Wrapping/PythonPackage/ [D:\T\vs10\SimpleITK-build\SimpleITK-build\Wrapping\_SimpleITK.vcxproj] [D:\T\vs10\SimpleITK-build\SimpleITK.vcxproj]
  
I don't know where that triple dot syntax came from or what it should mean. This is the custom command:

  add_custom_command( TARGET ${SWIG_MODULE_SimpleITK_REAL_NAME}
    POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy "${CMAKE_CURRENT_SOURCE_DIR}/PythonPackage/ez_setup.py" "${CMAKE_CURRENT_BINARY_DIR}/PythonPackage/"
    COMMAND ${CMAKE_COMMAND} -E touch "${CMAKE_CURRENT_BINARY_DIR}/__init__.py"
    COMMAND ${PYTHON_EXECUTABLE} "${CMAKE_CURRENT_BINARY_DIR}/PythonPackage/setup.py"
    install
    COMMENT "Installing python module to the virtualenv" )

Thanks,
Brad
