Lets squash that commit into this one, so we can see how it is used when
it is added.

That may be the directory that VS uses when building git, but it is
possible to specify a different build directory when running cmake.

I'm not sure about using env on windows, can we use ${SH_EXE} -c instead
to avoid creating an extra process?
COMMAND ${SH_EXE} -c [[GIT_TEST_BUILD_DIR="$1"; . "$2"]] "${tsh}"

I'm really not keen on hard coding the CMAKE_BINARY_DIR. One of the
positive things about dscho's approach is that it does not hard code the
build directory. I'm not convinced this approach is an improvement.
