Unknown CMake command "idf_build_get_property".

[xXWesleyXx eckz]

hello,

i'd like to start off saying i'm an intern with no ESP programming experience so please forgive because I this question will probably not be asked correctly.

We have a bunch of code that has been in an ESP32 before but that has been done by an external company and they won't share a thing unless they get a lot of money.
So i've been trying to do this for the past 2 weeks but VSCode keeps nagging about a million different things.
The thing that bullies me currently is the following message:

Code: [Select all] [Expand/Collapse]

1. CMake Error at C:/Users/Wesley/esp/esp-idf/components/freertos/CMakeLists.txt:7 (idf_build_get_property):
2.   Unknown CMake command "idf_build_get_property".

I've been googling and googling but I cannot find anything on how to get this command to work.
I could go and change all the CMakeLists but then it gets very frustrating again when I want to use a new/different version of esp-idf.
Also that's a lot of CMakeLists to change.

This is my root makelist:

Code: [Select all] [Expand/Collapse]

1. cmake_minimum_required(VERSION 3.0)
2.  
3. #include($ENV{IDF_PATH}/tools/cmake/project.cmake)
4.  
5. project(main)
6.  
7. add_subdirectory($ENV{IDF_PATH}/components/freertos include EXCLUDE_FROM_ALL)
8.  
9. #include_directories(${PROJECT_SOURCE_DIR}/include)
10. #include_directories($ENV{IDF_PATH}/components/freertos)
11. #include_directories($ENV{IDF_PATH}/components/esp_common)
12. #include_directories($ENV{IDF_PATH}/components/xtensa)
13. #include_directories($ENV{IDF_PATH}/components/esp_rom)
14. #include_directories($ENV{IDF_PATH}/components/esp_timer)
15.  
16. add_executable(main ${CMAKE_CURRENT_SOURCE_DIR}/main.c)

EVERY freaking tutorial on the internet isn't fixing this problem and it's making my blood boil.
How in the name of Freddie Mercury can I get this and similar idf_blah commands to work

Regards,

Wesley

PS if you need more info please ask and I will try to supply it.

#include "bla" is C for 'include this'. #include "bla" in CMake is 'the following is a comment and should be disregarded: include "bla"'

I know what a comment is, that wasn't what I asked about, ignore the comments.

So why did you comment out 'include($ENV{IDF_PATH}/tools/cmake/project.cmake)' then? You don't get the ESP-IDF build system if you do that, which makes any ESP-IDF specific call fail.
