On arch I needed an additional file for the utf8cpp package. I copied both files from the conan github . freesynd 0.9 now builds & runs fine, I just uploaded the new PKGBUILD to https://aur.archlinux.org/packages/freesynd
Found https://github.com/conan-io/conan-center-index/blob/master/recipes/crcpp/all/conanfile.py which makes clear CRCpp by d-bahr is the correct dep. Now to figure out how to combine conan with pacman. I've created https://bbs.archlinux.org/viewtopic.php?id=312154 to get input from other archlinux users about this.
