Please don't use `${}` around variable inside `if()`, and quote the
string. CMake has a quirk with the `${}` inside if (expanded variable
will be treated as a variable if it is defined, or string otherwise).
Unquoted string will be seen as a variable if it's defined, string
otherwise. IOW, suggested command:
if (program STREQUAL "git" OR program STREQUAL "git-shell")
We also have another problem with quoted arguments could be interpreted
as variable or keyword if CMP0054 policy not enabled, too.
I think it's better to have it enabled, but it's not in the scope of
this patch.
