Comment (by mojca@…):

 Is the port compatible with `xercesc3`? I'm asking because in the current
 form it fails to compile for me as I happen to have `xercesc3` installed
 and `xercesc` is conflicting with it.

 I assume that you are also the developer of the software. It would be
 really helpful if `CMakeLists.txt` was in the top level dir. This is not
 to say that the software cannot be included in MacPorts as-is, but it
 would be great if future versions would try to change this.

 At the current state I would suggest to replace
 {{{
 worksrcdir          ${distname}/build
 patch.dir           ${workpath}/${distname}
 }}}
 with
 {{{
 configure.post_args ${worksrcpath}/build
 }}}
 and then to fix this upstream and move `CMakeLists.txt` one level up.
