What do you have to do to get Basel to "build" a target that its designers have never encountered? The biggest problem I have with modern build systems is that they invest a lot in building specific types of artifacts. For instance, you might be able to compile and link a C program in three or four lines. In exchange, they fail miserably to account for situations like statically linking raw binary data into an executable or facilitating the automation of a target image build. So it's usually easy to build a desktop application but not much else. How easy would it be to automate a complete Android image build in Bazel?
