Compiler / linker warnings when building HPX 1.11.0-rc1

[kordejong]

I am testing the build of the Conda packages of the upcoming version of HPX. All packages build fine, which is great. I collected the compiler and linker warnings which you may want to check. Most of them are easy to fix it seems.

Thanks @kordejong. I'm not sure how to fix the linker warnings that refer to the weak symbols, but I will fix the others.

@kordejong could you please try adding -DHPX_WITH_HIDDEN_VISIBILITY=On to your HPX cmake invocation to see if that fixes the linker warnings related to weak symbols?

I tried it and the warning does not disappear, unfortunately, and I run into issue #6653 again.

BTW, the linker warning is not a new thing. It is also in the logs of builds of previous HPX versions. Not sure if it is very important to fix now.
