So I think I was able to reproduce your exact issue by:

1. fixing the escape issue for GNU Make 4.2.1
2. compiling without GPU support (e.g. by using the default config.mk)
3. Switching on mixed compilation mode GPU support
4. Recompiling just the case, not the core library
5. => linker errors for the same symbols that you got

So your setup should be fixable by executing make clean-core additionally and then rebuilding (forgot to mention this before)

I am still looking into a general fix for the escape issue as escaping the include fixes 4.2.1 but breaks 4.4.1. Will keep you updated.
