CentOS7 install Mongo-C-Driver

After install mongo-c-driver success.
I find that , the version is too old.
And I still can’t find mongoc.h

Another question.
Do you konw why?
When I build mongo-c-driver source project, why can’t build success…

When I run
rpm -ivh mongo-c-driver-1.16.2-2.fc32.src.rpm
why have no effect.
