That will make platform specific naming be ignored. We use a string instead, to
let Waf tweak the target name correctly for us. The '#' prefix is to tell Waf
that the path is relative to bld.bldnode (instead of bld.path, which is the
default).
We need to remove CMakeCache.txt, otherwise cached variables would remain the
old value when they are removed from cmake_vars parameter.
We use `os.remove()` instead of `Node.delete()` because the latter removes the
node instance from its parent's children list. That makes the node be ignored
when storing persistent information after the build, thus the node signature
wouldn't be saved with that approach, which would make waf always think that
the task should be executed.
The default implementation takes into account the task's output and input
nodes. That isn't very well applicable for cmake tasks, so we define proper
uid() methods.
That allows options being declared where they're really used. Additionally, we
load ardupilotwaf after the other tools so that we can create our groups after
all non-ardupilot option groups are created. That makes our groups appear as
the last ones in the help message, which makes it easier to locate them.
The gtest header uses lots of undefined macros, showing lots of warnings
if we enable -Wundef. Ideally we could use a #pragma to ignore the
warning only from the correct header, but this currently doesn't work
with g++ - see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431
So for now we disable the warning completely when compiling gtest or any
test that uses its header.

Copy the missing warnings from AP_Common.h and reorder the warnings to
be more clear on intent. This will later let us remove the warnings from
the header.
By running waf with option -v, waf was complaining about the update_submodule
tasks having the same identifier. That happened because the default uid()
method depended on the class name, inputs and outputs. Since this type of task
doesn't have input nor output file, we need to override uid() so that it uses
the submodule path for the task identifier.
With this change, there's no need to verify if the submodule is initialized,
because the submodules in GIT_SUBMODULES are automatically initialized and
updated if necessary before the build tasks are performed.
One downside of this change is that Google Benchmark configuration is now done
only during build. However that is minor, since now there are easy ways to
separately build different targets and program groups, so that a fail in
benchmark build doesn't really affect the other targets.
That is a workaround so that one can use `waf bin tests`, for example. In our
context, the only restriction to the task generators creation is values defined
during configuration. Thus, ideally, the recursion and task generators creation
should be done only once for multiple build calls. We should do that in the
future.
Rationale:
1. That function creates a separate build context class instead of just
creating a wrapper for calling build (previous approach).
2. The check command isn't a build shortcut since there's no way of calling it
without using 'check' explicitly.
The following fixes where applied:
- Value for APM_BUILD_DIRECTORY must be prefixed with APM_BUILD_
- Renamed parameter name to sketchname, so we differentiate the real program
name from the legacy sketch name
- Use directory name instead of program name as argument for
_get_legacy_defines()
Bind functions used in wscripts to build context. Additionally, a new function
is created and also decorated with @conf, common_vehicle_libraries(), which
returns COMMON_VEHICLE_DEPENDENT_LIBRARIES. This patch is a preparation for
making wscripts use methods bound to the build context instead of using them
directly from ardupilotwaf.
