# This macro wraps the cmake 'project' command to add

# all of the IDF-specific functionality required

#
|
|
# Implementation Note: This macro wraps 'project' on purpose, because cmake has
|
|
# some backwards-compatible magic where if you don't call "project" in the
|
|
# top-level CMakeLists file, it will call it implicitly. However, the implicit
|
|
# project will not have CMAKE_TOOLCHAIN_FILE set and therefore tries to
|
|
# create a native build project.
|
|
#
|
|
# Therefore, to keep all the IDF "build magic", the cleanest way is to keep the
|
|
# top-level "project" call but customize it to do what we want in the IDF build.
