[CMake] Cannot find UpdateCommand or GITCommand configuration key.

[Bill Lorensen]

I have a project that uses VTK. The project uses git for its repository.

I get the subject message.

I have defined
set( CTEST_GIT_COMMAND "git" )
SET(UPDATE_COMMAND "${GITCOMMAND}")
SET(UPDATE_OPTIONS "${GIT_UPDATE_OPTIONS}")

How can I resolve this issue.
