[CDash] Revision status API endpoint returns empty list

[Elvis Stansvik]

Nevermind, it was a simple matter of adding a missing

     set(CTEST_GIT_COMMAND git)
     set(CTEST_UPDATE_VERSION_ONLY TRUE)

and

     ctest_update(SOURCE "${CTEST_SOURCE_DIRECTORY}")

to our CTestScript.cmake. The latter was the crucial part, otherwise
no Update.xml was generated.

BTW the set(CTEST_GIT_COMMAND git) was necessary, or I would get a

    Cannot find UpdateCommand or GITCommand configuration key.

error. Anyone know why it can't auto-detect the Git command? It has
obviously detected that the repo type is Git, so shouldn't it just
auto-detect the Git command at that point?

I notice that e.g. CMake itself does [1]

    set(CTEST_UPDATE_COMMAND "@UPDATE_COMMAND@")
    set(CTEST_UPDATE_OPTIONS "@UPDATE_OPTIONS@")

in their Templates/CTestScript.cmake.in to set CTEST_UPDATE_{COMMAND,
OPTIONS} variables from the ones detected in Modules/CTest.cmake, but
I'm hesitant to do the same as that would require us to turn our
CTestScript.cmake into a configure_file()-configured template to get
access to those variables, and that will be very awkward as you'd have
to run cmake prior to running ctest -VV CTestScript.cmake to confgure
the script :/
