Vitis math functions, sin, abs, not seen even though math.h referenced

[Xband]

Bug of the day, error;

"Description    Resource    Path    Location    Type
undefined reference to `sqrtf'    helloworld.c    /AxiTest/src    line 197    C/C++ Problem"

This comes up for sin, abs, and other math.h functions that should be properly linked as the library is "include"'ed. 

Found a solution posted in 2014 on the AMD site, https://adaptivesupport.amd.com/s/article/52971?language=en_US, 

But when I open my "C/C++ Build, Settings" my "Tool Settings" looks nothing like the picture, mine is mostly empty.  

I do not know where to apply the "m", there is not "ARM linker" option.  

Does anyone know where I can try to do this? 

Or another fix?

Thanks,
