graphviz FTBFS with cmake 4.x

[Zhang Wen]

The error message is as follows:

CMake Error at cmake/config_checks.cmake:18 (if):
if given arguments:
"PANGOCAIRO_FOUND" "AND" "VERSION_GREATER_EQUAL" "1.4" "AND" "Linux" "MATCHES" "Linux"
Unknown arguments specified

I've created a patch and submitted it to the upstream​https://gitlab.com/graphviz/graphviz/-/merge_requests/4405

The problem is "AND" in cmake has no short-circuit semantic but the upstream developer didn't understand that. Thus this only happens when pango is not installed.

And I'm almost sure this is not related to cmake-4 vs cmake-3.

I certainly did not have a problem with building with cmake.

All the options for graphviz are optionsal. the first entry is:

Pango-1.56.3, with Cairo-1.18.4, Xorg Libraries, Fontconfig-2.16.2, libpng-1.6.49, 
to generate images in bitmap SVG, postscript, PNG, and PDF formats, or to 
display the image on screen. The PNG output is required for building gegl-0.4.62. 

Perhaps we should promote that line to recommended.

Promote Pango and friends to recommended in graphviz.
