Use ESP-IDF components from outside project directory

I have multiple IDF projects and many of them use the same components. Instead of having a copy of the components in each project's directory, I want to place all the components in a global directory and use them in all my projects. I'm using ESP-IDF v.4.4.4 in VSCode. Here is the structure I want:

main_directory
|
|__global_components
|  |__component1
|  |__component2
|  |__component3
|
|__project1
|  |__CMakeLists.txt
|  |__sdkconfig
|  |__main/
|  |  |__CMakeLists.txt
|  |  |__src.c
|  |__build
|
|__project2
|  |__CMakeLists.txt
|  |__sdkconfig
|  |__main/
|  |  |__CMakeLists.txt
|  |  |__src.c
|  |__build
|
|__project3

This is what the CMakeLists.txt file in my project directory looks like:

# The following lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(esp32_project)

How will I have to change this file?

This is what the CMakeLists.txt in my project/main directory looks like:

idf_component_register(
    SRCS "crypto.cpp" "image.cpp" "main.cpp"
    INCLUDE_DIRS "."
)

Will I have to change this file too? Thanks for the help. If I am approaching this in the wrong way and there is a better way to manage the problem I would love to know.

I tried set(EXTRA_COMPONENT_DIRS $(PROJECT_PATH)/../global_components/) but that did not work.

Try to define

set(EXTRA_COMPONENT_DIRS $(PROJECT_PATH)/../global_components/)

in your root CMakeLists.txt file before you declare the project. Like this:

set(EXTRA_COMPONENT_DIRS $(PROJECT_PATH)/../global_components/)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(esp32_project)
