# The cmake version that is available on Ubuntu 16.04 is 3.5.1. While Firestore
# itself requires cmake 3.5, it depends on leveldb which requires cmake 3.9
# (https://github.com/google/leveldb/blob/master/CMakeLists.txt#L5).
# There is an open issue (https://github.com/google/leveldb/issues/607) to
# lower the required cmake version of leveldb. Therefore, we need to download
# a newer version of cmake until leveldb lowers the required version or a newer
# cmake version becomes available in the OSS Fuzz environment.
