sudo yum install libcxl-devel dapl-devel

A make gives the following error.

...

There is no file name libocxl in /usr/include, changing the include to libcxl.h leads to more errors.

libcxl is for capi1 (power8) or capi2 (power9) libocxl is for opencapi Based on the name of your source file, I'm guessing you're interested in opencapi. Can you confirm? If so, then RHEL7.5-ALT doesn't support opencapi. Support is added in RHEL7.6-ALT (a.k.a Pegas 1.2). You will also need to make sure the libocxl package is installed.
