# Building re2 which is thread-safe and re2_st which is not.
# re2 changes its state during matching of regular expression, e.g. creates temporary DFA.
# It uses RWLock to process the same regular expression object from different threads.
# In order to avoid redundant locks in some cases, we use not thread-safe version of the library (re2_st).
