cmake: use target aliases from local Google Test checkout. (#1083)
* cmake: use target aliases from local Google Test checkout. `ABSL_FIND_GOOGLETEST` is a dependent option, it is always `OFF` when `ABSL_USE_EXTERNAL_GOOGLETEST` is `OFF` (i.e. when Google Test is checked out locally). `GTest::` target aliases are to be added only if `find_package(GTest)` has been actually used. * cmake: clarify adding GTest:: aliases.
