CentOS 8 doesn't appear to have pmLocalPMDA - where did it go?

I'm building a cockpit project that used to build fine on CentOS 7 but is having issues with CentOS 8. After resolving several issues I have it compiling now, but I get this error now:

error: implicit declaration of function 'pmLocalPMDA'; did you mean 'pmSpecLocalPMDA'? [-Werror=implicit-function-declaration]

Any idea why pmLocalPMDA isn't being found?

Note: pmSpecLocalPMDA() is different from pmLocalPMDA().
