<pre>
    The GAMESS team wants to use nightly binaries for CI testing to avoid building Flang from source every time.  The Flang binaries from apt.llvm.org do not use the CMake option `-DFLANG_RUNTIME_F128_MATH_LIB=libquadmath` and thus do not have all the features they need.

```
/usr/bin/ld: qeigen.o: in function `qjacdia_':
/gamess/object/qeigen.f:200:(.text+0xe1c): undefined reference to `_FortranASqrtF128'
/usr/bin/ld: /gamess/object/qeigen.f:201:(.text+0xe51): undefined reference to `_FortranASqrtF128'
/usr/bin/ld: /gamess/object/qeigen.f:202:(.text+0xe70): undefined reference to `_FortranASqrtF128'
```

I apologize if this is a dumb question.  If there's a license issue with shipping libquadmath support then I guess it is unsolvable.
