Thank you.

I couldn't build it because gperftools currently has a failing test.

IIUC correctly, these are the suggested build options in the README. It
may be worth adding a comment about it since this looks a bit
opinionated.

This does not belong to the set of suggested build options. Is there
a particular reason to activate it? If so, would it make sense to add
a comment about it?

I also see there is a "BUILD_SHARED_LIBS" flag, off by default. Would it
make sense to activate it?

In both comments, there should be a single semicolon and no full stop.

Could you send an updated patch?
