cmake: Allow selecting toolchain file based on config Refactor IDF "project" functionality under a wrapping of the default "project" command, so we can tweak it a bit... Will need more testing in other environments. 2018-02-14 22:38:58 -05:00			`if(BOOTLOADER_BUILD)`

cmake: fix custom bootloader issue Issue is that when users creates a custom bootloader from $IDF_PATH/components/bootloader. Parent project build uses the copy but bootloader subproject build uses the original still. The issue is solved by passing the custom bootloader as extra component directory so bootloader build knows to use the new copy (itself) in the build. 2019-05-14 23:40:57 -04:00			`SOURCE_DIR "${CMAKE_CURRENT_LIST_DIR}/subproject"`
