[CMake] ExternalProject module in 2.8.2 completely broken with respect to GIT?

[kent williams]

Please tell me someone else encountered this and it's fixed. I'm going
to have to make a patched version of ExternalProject.cmake a part of
my project until it is.

In CMake 2.8.2 ExternalProject.cmake, there is no consistency on the
capitalization of the Git_EXECUTABLE variable -- which is what gets
set by
find_package(Git).

There are instances of GIT_EXECUTABLE and git_EXECUTABLE.  Once I fix
those everything works fine.
