Hm? CMake's list separator is the semicolon:

`(list APPEND ...)` doesn't work on cache variables. If I were to use the (set
CACHE FORCE) idiom instead, it would append lldb each time a configure occurs.
The idea here is to have FUCHSIA_ENABLE_LLDB affect the defaults, but to
respect whatever's already in the CMake cache otherwise.
