Lots of code is duplicated across build_binary.mk, build_shared_lib.mk and build_static_lib.mk. We should attempt to remove the bloat and have common files for repeated target code.

We might want to override arguments to our target binaries. In order to do so, let's add a RUN_ARGS environment variable containing such arguments.

Then we would be able to use it like this:

make args_my_binary="-h" run_my_binary

And it would be equivalent to building and running your binary like this:

./build/targets/my_binary -h

Create test target able to link to googletest.

It is worth exploring the cost of embedding compilers and tools to simplify installation and improve build reproducibility. Of course it would make sense to add these tools as external repositories part of the repo manifest.

No need to support LOCAL_MULTILIB := both for now. Just either 32 bit or 64 bit.

Though this can be generated externally with tools such as compdb, embedding the generation of the compilation database for Clang would be quite nice.

All targets should be documented in the variables it uses and how it uses them.

It would be very nice if we would be able to do the following operations per target:

• Build
• Clean
• Run (For binaries only)

Run should also properly set the LD_LIBRARY_PATH.

Create a test build that verifies targets work as expected.

Using shared libraries is now somewhat annoying, as the LD_LIBRARY_PATH needs to be updated with all directories containing a shared library. Instead we should have all library targets in the same folder, keeping the exports specific per target.

Instead of having to redefine for every target common settings like compiler, sysroot, system includes, target triplet, etc, create builtin configurations that can be configured with a variable such as LOCAL_BUILTIN_COMPILER and LOCAL_BUILTIN_ARCH

It would be even nicer to allow the user to create their own customized targets as well and use them with these variables if the builtins are not good enough or need customization.
