- Check emcc versions *if* `EMSDK_PATH` was explicitly set, IOW, workloads are not in use
Convert the assemblies only if needed.
- If the inputs are older than the outputs, then no work needs to be
done
- The inputs consist of the assemblies to scan, and a list of pinvoke
modules.
- Timestamps are used for the assemblies
- And for the pinvoke modules list, we save that in a cache file, and
use that to determine if any work needs to be done.
`EmccCompile` task build compiles some `.c` files, but skips them if the output files are already up-to-date. But the build always emits a `Compiling native assets with emcc with ..` message, which suggests that there is some native build being run. Instead, emit this message only if `EmccCompile` actually did any work.
