I am attempting to create my own docker image on Centos 7.  During the build, I get the following error message during the "make all" phase.
----------------------------------------------------------------------

I checked and the mysql.h exists in the /usr/include/mysql directory.

Any thoughts?

FYI, here is my Dockerfile
