Hello! I don't think that it is a bug, but not a feature request at all. After update to 4.0-rc we tried to use new build system to be up to date. Before we use component.mk file to set CXX flags belongs to required component. CXXFLAGS +...
So, if a user wants to set this variable (as a cache variable - there is no other option for a user), the new value is used as a redefinition of compiler-specific flags. A project may modify that value, but only as a non-cache one (as you do by set(CMAKE_CXX_F...

I don't know why conda-build sets CXXFLAGS and CFLAGS on macOS. There is probably a good reason. The behavior is documented here: https://docs.conda.io/projects/conda-build/en/latest/user-guide/environment-variables.html However, these variables cause unpleasant and difficult-to-solve build ...
