Is there a better way to add cpp code? about opencascade.js HOT 2 OPEN

I've been thinking about this problem for a while and what I've come up with is implemented in another project called libclangjs, here. Libclangjs adds JavaScript / WASM bindings to llvm's libclang (similar to how OCJS adds JavaScript / WASM bindings to OCCT - but much simpler). There is a fairly minimal test and some docs that explain how it works. In summary:

• The bindings and relevant headers are published as a CMake package, that can be added via CMake's find_package call to your custom CMake project (which builds an "executable", i.e. the .js and .wasm files, you want to use in your JS project).
• This CMake package is published via NPM. That might be a bit unusual, but I think it's an easy way of publishing that package, which should integrate nicely with commonly used JS development tools. This should also work nicely with a monorepo layout, where the "custom build" of OCJS is just another package that can be installed by other packages inside that repo.
• C/C++ code can then be written "like usual" in any other CMake-based project.

I believe this is much cleaner and lightweight than the current solution of adding c++ code to a yaml file and starting a huge Docker container for each compilation. If you have any thoughts / opinions on this, please let me know.

PS: This ignores the fact that the custom build yaml-files also specify which bindings should be included. This would be a separate issue under this proposal.

It looks great ! If there are any examples, I would be happy to test.
