Sure. The next step is try to integrate this into the scripting I have to generate the cmake. This way we can create a full build with the tests working.
Also, we need to figure out how to approach Boost.Configâs require rule it adds with cmake. It probably just be config check, and the user can write their own conditional in cmake.
There is a few changes I made to the testing in this example so it works on the small subset(config and core depend on type traits), but for the full build these changes wonât be necessary.
