Compiles, links, and builds an ELF binary for the target named <target-name>. It builds an ELF file for the application specified by the app
variable for the target-name
target. The image can be loaded and run on the hardware specified by the bsp
variable for the target. The command creates the ‘bin/’ directory under the project's base directory (that the newt new
command created) and stores the executable in the ‘bin/targets/<target-name>/app/apps/<app-name>’ directory. A manifest.json
build manifest file is also generated in the same directory. This build manifest contains information such as build time, version, image name, a hash to identify the image, packages actually used to create the build, and the target for which the image is built.
You can specify a list of target names, separated by a space, to build multiple targets.
