Separate build and source directories have been enabled
by default for selected recipes where it is known to work
(a whitelist) and for all recipes that inherit the
cmake
class.
In future releases the
autotools
class will enable a separate build directory by default as
well.
Recipes building Autotools-based
software that fails to build with a separate build directory
should be changed to inherit from the
autotools-brokensep
class instead of the autotools
or
autotools_stage
classes.
