To load all paths use

source setup.sh

Building:

cmake -B build
cmake --build build

Very verbose log:

cmake --build build -- -vvv -DEXTRA_FLAGS="-save-temps" > build.log 2>&1

Building in parallel with cmake:

cmake --build build -- -j 10

Can still be used for building after creating the build configuration, but don't use west build before since it needs a BOARD definition, which is already specified in the CMakeLists.txt.
