# FindBabbleSim module for locating BabbleSim |
|

|
# The module defines the following variables: |
|
# |
|
# 'BSIM_COMPONENTS_PATH' |
|
# Path to the BabbleSim components source folder |
|
# |
|
# 'BSIM_OUT_PATH' |
|
# Path to the BabbleSim build output root path (under which libraries and binaries) are kept |
|
# |
|
# We first try to find it via the environment variables BSIM_OUT_PATH and BSIM_COMPONENTS_PATH. |
|
# If these are not set, as a fallback we attempt to find it through west, in case the user |
|
# fetched babblesim using the manifest. |
|
# Note that what we find through the environment variables is meant to have precedence. |
|
# |
|
# If BabbleSim cannot be found we error right away with a message trying to guide users |
