* Add CMake build
Allows to build and link FreeRTOS using CMake build system.
From top-level project it looks like this:
set(FREERTOS_PORT_GCC_ARM_CM4F ON)
set(FREERTOS_CONFIG_FILE_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} CACHE STRING "")
add_subdirectory(third_party/FreeRTOS-Kernel)
Where FREERTOS_PORT_GCC_ARM_CM4F is FreeRTOS port name.
freertos is target name, which can be used in target_link_libraries()
* Add feature to set custom heap source file
Example how to set it from top-level project:
set(FREERTOS_HEAP ${CMAKE_CURRENT_LIST_DIR}/path_to/my_heap.c CACHE STRING "")
* Set cmake_minimum_required to 3.15
* Fail build when FREERTOS_CONFIG_FILE_DIRECTORY not set
* Rename library to freertos_kernel
* Rework FREERTOS_PORT option to act as combobox
* Use freertos_kernel_port cmake target
* Split port sources multiline
