Support older utfcpp versions with utf8cpp CMake target (#1243) (#1244)

ufleisch · web-flow · commit 1bd0d711ca81 · 2024-08-15T12:44:17.000+02:00
This affects for example openSUSE Leap 15.6, which installs
utfcpp 3.2.1 in its own folder.
Now not only utf8::cpp, but also utf8cpp is supported as a CMake
target.
