You can choose HashLink instead of hxcpp for Kinc-based targets when running Kha/make:

• windows-hl
• linux-hl
• osx-hl
• android-hl
• ios-hl

This only supports hlc, the HashLink VM is not supported and there are no plans to do so. In general HashLink compiles much faster but runs slower than hxcpp (most notably HashLink's garbage collector is slower and HashLink does not support Kha's SIMD optimizations). The favored backend in Kha is still hxcpp, it's better tested and more optimized.
