Gil d4e86ba091 Fixes for compatibility with builds in firebase-cpp-sdk (#4984)
* Don't modify CMAKE_CXX_FLAGS

* Avoid conflict on RANDOM_FILE

* Only conditionally build tests

* Remove alias provided by the upstream build

* Set SOURCE_DIR and BINARY_DIR for each external library

* Compute repo root without git

This supports building Firestore from a source archive

* Make empty files C++

This makes it possible to compile with a single set of flags for every
cc_library.
