Hi,

I played around with the ExternalProject unit tests and was able to reproduce my problem with the current HEAD ExternalProjects.cmake file. It boils down to *not* adding the UPDATE_COMMAND "" line:

1.) In CMake/Tests/ExternalProject/CMakeLists.txt:487 remove (or comment in) the UPDATE_COMMAND argument 2.) Build the "TutorialStep1-GIT-bytag" project with VisualStudio 2010 (I am using the Express Edition). You will get:

1>------ Rebuild All started: Project: TutorialStep1-GIT-bytag, Configuration: Debug Win32 ------
1>  Creating directories for 'TutorialStep1-GIT-bytag'

========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

So all other steps after the update step are ignored.

In CTK, we rely on the default update command for git and it works in Visual Studio 2008. Any ideas how to fix this will be greatly appreciated.

Thanks,
Sascha

For example, when I build the ExternalProject test and build only the project "TutorialStep5-Local", I get the following output:

Do you see any "Performing XXX step" or "No XXX step" output after the download occurs...?

        Hi,

        Thanks David and Yuri for the information. In my case (with
        CTK), there are no error messages. The download step is
        successfully completed and the following steps are just
        skipped. VS then reports that everything was successfull (or
        up-to-date).

        I will play with your test cases and my VS 2010 installation.

        Thanks,
        Sascha

                    Hi,

                    there is something very strange going on. The
                    generated VS 2010 projects
                    (I am using the Express editions, 32bit) for the
                    external dependencies like
                    DCMTK, Log4Qt, etc. only call the download step of
                    the ExternalProject_add
                    call in our superbuild scripts. The projects are
                    not configured and build.

                    Did anybody experience the same? I tried with and
                    without the VS 2010 SP1
                    and with CMake 2.8.4 and 2.8.5.

                    Thanks,
                    Sascha

                        Hi Folks,

                        I would like to get Visual Studio 2010
                        compatibility for CTK.

                        Currently, it looks like I will have to copy
                        ExternalProject.cmake to
                        CTK for the CMAKE_CACHE_ARGS argument. Then a
                        couple of small
                        modifications should do.

                        Any other ideas or objections?

                        Thanks,
