there are 2 issues in the configure

checking whether to use Cairo... "yes"
Package cairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo.pc'
to the PKG_CONFIG_PATH environment variable

checking cairo.h usability... yes
checking cairo.h presence... yes
checking for cairo.h... yes
Package cairo was not found in the pkg-config search path.

not sure what virtual:world is for.

though, config seems to be ok

  Cairo support:              yes
  DWG support:                no
  FFTW support:               yes
  FreeType support:           yes

it seems to be an issue of the build environment (results of googling the error message)

looking here in my build environment

no chance to do a local test build here.

not sure how to test it in the CI build environment

@ninsbl any idea?

maybe some hints in a github issue

fixed by installing mingw-w64-x86_64-pkg-config or mingw-w64-i686-pkg-config instead of pkg-config.

Here is the full log (hopefully accessible):

As far as I see this is already used - see:

@hellik your remark isn't clear to me...

Sorry for my silence n this. For some reasons I do not receive GH notifications any more although I am watching issues...

Probably the issue is really the PKG_CONFIG_PATH., see e.g. msys2/setup-msys2#171

Will try to have a look at this the comming days...

The culprit is likely here:
https://github.com/OSGeo/grass/runs/7513175054?check_suite_focus=true#step:5:242

Using msys2-setup@v2 action seems to help (tests are currently running in my fork...)...

I suggest to abandon this PR in favor of #2508...

Yes, it was just a test.
Closing.
