[Linux] Error when compiling with `HXCPP_TRACY`

### Error
```
Error: In file included from /.../TurnBasedRPG/.haxelib/hxcpp/git/src/hx/TelemetryTracy.cpp:2:
/.../TurnBasedRPG/.haxelib/hxcpp/git/include/hx/TelemetryTracy.h:9:10: fatal error: /.../TurnBasedRPG/export/linux/obj/obj/linux64/__pch/runtime/hxcpp.h: File or directory does not exist
9 | #include
| ^~~~~~~~~
compilation terminated.
```
##
Adding `#include ` to `hxcpp.h` like below fixes the error for me but I'm not sure if that's the correct way to solve it.
