Previously, this compiler flag was not being applied regardless of CONFIG_SPIRAM_CACHE_WORKAROUND setting. Explanation: add_compile_options() only applies to source files added after the function is run, or in subdirectories added after the function is run. In this case, no new source files were being added after this function was run.
