"""PlatformIO build script (pre: runs before other Meshtastic scripts).

ClusterFuzzLite executes in a different container from the build. During the build,
|

|
|
attempt to link statically to as many dependencies as possible. For dependencies that
|
||
|
|
do not have static libraries, the shared library files are copied to the output

directory by the build.sh script.
