Description: Trying to install both “cmark” and “cmark-gfm” results
in both packages trying to install their headers in the same location.

/usr/include/cmark.h exists in both 'cmark' and 'cmark-gfm'
/usr/include/cmark_export.h exists in both 'cmark' and 'cmark-gfm'
/usr/include/cmark_version.h exists in both 'cmark' and 'cmark-gfm'
Errors occurred, no packages were upgraded.

These two packages install libraries with different names, and it should be possible
to install both in parallel. I would suggest moving the headers from “/usr/include”
into “/usr/include/${pkgname}” and making sure that when building the pkg-config
“.pc” files and the “.cmake” include files include the corresponding “-I…” compiler
flag.


Additional info:
* package version(s): cmark 0.28.3-1, cmark-gfm 0.28.3.gfm.14-1
* config and/or log files etc.


Steps to reproduce:

1. Try to install both packages: pacman -Sy cmark{,-gfm}
