[Cmake-commits] Git Fails to Pull with ExternalProject_Add

[Constantine Zakkaroff]

Hello ALL,

I have a SuperBuild project depending on some other project cloned from 
a git repository. However I've noticed the cloner repository doesn't get 
updated when I rebuild the project.

Is it right to expect the repository to be updated automatically? Or 
does it need to be done manually?

Here's how the call to ExternalProject_Add looks in my project:

   ExternalProject_Add(${proj}
     GIT_REPOSITORY ${${proj}_REPOSITORY}
     GIT_TAG ${${proj}_GIT_TAG}
     SOURCE_DIR ${proj}
     BINARY_DIR ${proj}-build
     CMAKE_GENERATOR ${gen}
     CMAKE_ARGS
       -Wno-dev
       --no-warn-unused-cli
       ${COMMON_EXTERNAL_PROJECT_ARGS}
       ${${proj}_CMAKE_OPTIONS}
     INSTALL_COMMAND ""
     DEPENDS ${${proj}_DEPENDENCIES}
   )

Many thanks,
Constantine
