Errors when linking math lib. - pdaragon - 25-09-2020

Hello,
I try to import a Keil project published by Semtech (firmware of the LoRa SX1261 evaluation kit).
I almost succeeds, but face 5 remaining errors when the linker searches for <math.h> following functions: rint, round, floor, ceil.
I tried to change several options in "Linker setttings/Library selection", but without success.
Please could you help.
I attach the .ebp project with this post (STM32L476RG HAL source files has been removed to limit zip file size to less than 1Mb).
Thanks and regards
Pascal
