This solves that problem, but eliminates the ability to configure the builder.
What if you added a new member and callback along the lines of:
```c++
std::optional<std::string> OrcRuntimePath;
llvm::unique_function<LLJITBuilder(&JITConfig)> MakeJITBuilder =
makeDefaultJITBuilder;
```
then in the setup path you'd have something like:
```c++
if (!Cfg.OrcRuntimePath) {
if (OrcRTPath = getOrcRuntimePath(TC))
CfgOrcRuntimePath = std::move(*OrcRTPath);
else
return OrcRTPath.takeError();
}
auto JITBuilder = MakeJITBuilder(Cfg);
if (auto JOrErr = JITBuilder.create())
J = std::move(*JOrErr);
else
return JOrErr.takeError();
...
```
The extra indirection gives you the opportunity to ask the driver for the path
(if one isn't provided) while still giving the client the opportunity to
configure the LLJITBuilder.
