scripts: west_commands: build: support --cmake-opt

[thorsten-klein]

Why?

When using west aliases, it is helpful for users to give cmake arguments, e.g. to make building specific variants as easy as possible. Currently -- must be used, e.g.

[alias]
build-llvm = build -- -DZEPHYR_TOOLCHAIN_VARIANT=llvm
build-codechecker = build -- -DZEPHYR_SCA_VARIANT=codechecker
build-llvm-codechecker = build -- -DZEPHYR_TOOLCHAIN_VARIANT=llvm -DZEPHYR_SCA_VARIANT=codechecker

With this approach it is not possible anymore to specify west arguments when the alias is used (e.g. board -b native_sim), as the argument comes behind -- and therefore it is handled as cmake argument.

Solution

Support for --cmake-opt argument is added which allows specifiying cmake options via west build --cmake-opt=<arg>, in order to avoid -- in alias commands. This argument can be specified multiple times, e.g.

[alias]
build-llvm = build --cmake-opt=-DZEPHYR_TOOLCHAIN_VARIANT=llvm
build-codechecker = build --cmake-opt=-DZEPHYR_SCA_VARIANT=codechecker
build-llvm-codechecker = build --cmake-opt=-DZEPHYR_TOOLCHAIN_VARIANT=llvm --cmake-opt=-DZEPHYR_SCA_VARIANT=codechecker

# or even easier: build-llvm can be reused
build-llvm-codechecker = build-llvm --cmake-opt=-DZEPHYR_SCA_VARIANT=codechecker
