I have just hit this same problem with the latest scnlib port in vcpkg. I'll downgrade for now.

this is the build patch for building with simdutf 5.0.0, #102

the patch actually needs some update for simdutf 5.2.2, Homebrew/homebrew-core#167800

[imwints]

I'm not sure if this is the ideal solution, since 5.x didn't introduce any breaking changes it would be weird to just not support it. Version ranges from cmake don't work either since it needs to match major + minor, so 4.0.0 < 5.2.2 would only match 4.0.x and 5.2.x, nothing in between (5.0.x etc). I've not tested it, but I wrote this patch and I've locally tested replacing

find_package(simdutf 5.2.0 CONFIG)
# with
find_package(simdutf 5 CONFIG)

which correctly finds simdutf-5.2.2.

The CI is acting up, but I believe this should be good since 97baaf2 and 5c4b91e. I'll cut a release with this, soon, unless there are issues with this.

Thanks for bringing this up -- managing dependencies with CMake is really something.
