Subject: esp32: disable stack protector for startup code (CMake)
X-Git-Tag: v3.2-beta3~3^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1e674fb4ed5d89916c8662f6720811c684448018;p=esp-idf

esp32: disable stack protector for startup code (CMake)

Files where stack protector is initialized should not be compiled with
stack protector enabled. This was done for Make but missing for CMake.

Fixes https://github.com/espressif/esp-idf/issues/2990.
