# Component common makefile
|

#
|
||
|
|
# This Makefile gets included in the Makefile of all the components to set the correct include paths etc.
|
||
|
|
# PWD is the build directory of the component and the top Makefile is the one in the
|
||
|
|
# component source dir.
|
||
|
|
#
|
||
|
|
# The way the Makefile differentiates between those two is by looking at the environment
|
||
|
|
# variable PROJECT_PATH. If this is set (to the basepath of the project), we're building a
|
||
|
|
# component and its Makefile has included this makefile. If not, we're building the entire project.

# This Makefile requires the environment variable IDF_PATH to be set
|
||
|
|
# to the top-level directory where ESP-IDF is located (the directory
|
||
|
|
# containing this 'make' directory).
