How to check the esp-idf version in Kconfig.projbuild

[nopnop2002]

I want to do something like this.
But I don't know how.
Only the major version of IDF needs to be checked.
Not minor versions.

Code: Select all

menu "Application Configuration"

if IDF_VER_MAJOR == 5
    config LEGACY_DRIVER
        bool "Force legacy i2c driver"
        default false
        help
            Force legacy i2c driver.
endif

endmenu
