Do not modify the code in this directory. It has been copied from its upstream
git repo [1]. When submodules are introduced this directory can be made a

class AutoOption:
"""
This class represents an auto option that can be used in conjunction
with the waf build system. By default it adds options --foo and
--no-foo respectively to turn on or off foo respectively.
Furthermore it incorporats logic and checks that are required for
these features.

An option can have an arbitrary number of dependencies that must be
present for the option to be enabled. An option can be enabled or
disabled by default. Here is how the logic works:
1. If the option is explicitly disabled, through --no-foo, then no
checks are made and the option is disabled.
2. If the option is explicitly enabled, through --foo, then check
for all required dependencies, and if some of them are not
found, then print a fatal error telling the user there were
dependencies missing.
3. Otherwise, if the option is enabled by default, then check for
all dependencies. If all dependencies are found the option is
enabled. Otherwise it is disabled.
4. Lastly, if no option was given and the option is disabled by
default, then no checks are performed and the option is
disabled.

To add a dependency to an option use the check, check_cfg and
find_program methods of this class. The methods are merely small
wrappers around their configuration context counterparts and behave
identically. Note that adding dependencies is done in the options
phase and not in the configure phase, although the checks are
acutally executed during the configure phase.

Custom check functions can be added using the add_function method.
As with the other checks the check function will be invoked during
the configuration. Refer to the documentation of the add_function
method for details.

When all checks have been made and the class has made a decision the
result is saved in conf.env['NAME'] where 'NAME' by default is the
uppercase of the name argument to __init__, with hyphens replaced by
underscores. This default can be changed with the conf_dest argument
to __init__.

The class will define a preprocessor symbol with the result. The
default name is WITH_NAME, to not collide with the standard define
of check_cfg, but it can be changed using the define argument to
__init__. It can also be changed globally using
set_auto_options_define.

"""
This class is the foundation for the auto options. It adds an option
--foo=no|yes to the list of options and deals with all logic and checks for
these options.

Each option can have different dependencies that will be checked. If all
dependencies are available and the user has not done any request the option
will be enabled. If the user has requested to enable the option the class
ensures that all dependencies are available and prints an error message
otherwise. If the user disables the option, i.e. --foo=no, no checks are
made.

For each option it is possible to add packages that are required for the
option using the add_package function. For dependency programs add_program
should be used. For libraries (without pkg-config support) the add_library
function should be used. For headers the add_header function exists. If
there is another type of requirement or dependency the check hook (an
external function called when configuring) can be used.

When all checks have been made and the class has made a decision the result
is saved in conf.env['NAME'] where 'NAME' by default is the uppercase of the
name argument to __init__, but it can be changed with the conf_dest argument
to __init__.

The class will define a preprocessor symbol with the result. The default
name is HAVE_NAME, but it can be changed using the define argument to
