[Pkg-gmagick-im-team] imagemagick 7 needs cmake adjustments?

[Steven Robbins]

Hello,

I got a note that digikam failed to build with new imagemagick 7.  The specific 
error was that including <Magick++/Include.h> failed:

In file included from /usr/include/ImageMagick-7/Magick++/Include.h:16,
                 from /usr/include/ImageMagick-7/Magick++.h:12,
                 from /<<PKGBUILDDIR>>/core/libs/dialogs/libsinfodlg.cpp:77:
/usr/include/ImageMagick-7/MagickCore/magick-config.h:25:10: fatal error: 
MagickCore/magick-baseconfig.h: No such file or directory
   25 | #include "MagickCore/magick-baseconfig.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

This stemmed from a lack of -I directive on the compile line for the 
architecture-dependent directory.  In previous builds, the cmake config was 
able to locate two include dirs.  

-- ImageMagick_INCLUDE_DIRS:           	/usr/include/ImageMagick-6;/usr/
include/x86_64-linux-gnu/ImageMagick-6

When building against imagemagick 7, the second one is missing -- which is 
where "magick-baseconfig.h" is located.

Ultimately this turns out to be due to a change in imagemagick directory 
names:

/usr/include/x86_64-linux-gnu/ImageMagick-6/magick
/usr/include/x86_64-linux-gnu/ImageMagick-7/MagickCore

This change forces adaptation in the cmake module because currently it 
searches for "magick/magick-baseconfig.h" when locating the arch include dir.  
It's curious that the cmake does have changes already in place for 
ImageMagick-7, but not for the magick --> MagickCore change.

The reason for this email is to ask whether this change is indeed from 
upstream or is it a Debian decision?  If the latter, then would you consider 
changing back?  Otherwise, heads-up to the cmake team that the module needs 
changing.

In the case of Digikam, it ships its own cmake module so I fixed my problem 
there.  See https://salsa.debian.org/debian/digikam/-/commit/
