…build. Calling `west build --build-opt="-v" --build-opt="-j=<n>"` passes the build options to `cmake --build ... -- <build-opt>` which again is passed to the native build tool, such as ninja or make. However, when ExternalProjects are used in CMake, such as in TF-M or sysbuild builds then those extra build options are only passed to the first image build and not those build as external projects. CMake supports environment variables for those flags, so translate verbosity and number of jobs to those environment variables and thereby support those flags for all images when specified by the user. Signed-off-by: Torsten Rasmussen <[email protected]> (cherry picked from commit 63cf79b)
…nv variables Sysbuild may include several images and when using ninja as build tools then build options like `ninja -v` or `ninja -j <n>` is only consumed by the top-level build folder, which is sysbuild itself. CMake supports setting number of jobs or verbosity using environment variables. Document this feature in the Building with sysbuild section.
