boilerplate.cmake not found because ZEPHYR_BASE isn't set

Question

Hi, 
 
 I'm very confused by this error. 
 I have a project with the following CMakeLists.txt file 
 cmake_minimum_required(VERSION 3.20.0)

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(bike_finder)

target_sources(app PRIVATE src/main.c)
//... more target sources

# NORDIC SDK APP END
zephyr_library_include_directories(.) 
 When the project is tried to be built at the startup of VScode, I get the following error message 
 
 When I open a terminal, I ran echo $ZEPHYR_BASE, but it came out empty. Therefore, I go into the nRF Connect SDK folder that I'm using (v2.2.0-rc1), run source zephyr/zephyr-env.sh and then the terminal finally recognizes where ZEPHYR_BASE is. 
 To rebuild, I just do a dummy modification to the file (use :w since I'm using vim within vscode), and then application tries to rebuild again, but I keep the same error. 
 If I go to the nRF Connect extension section, I see my folder under applications, but it's followed by "no build configurations", because of this problem. 
 What should I do?

Hi, Prepending zephyr to includes is introduced with Zephyr v3.x.x namespace change . It is not recommended to use old include paths. Having said that, there is a KConfig configuration option CONFIG_LEGACY_INCLUDE_PATH but it is deprecated and expected to be removed. You could use Python script migrate_includes.py which is located in zephyr/scripts/utils/ to perform conversion. Best regards, Dejan
