You might find that there are groups of recipes or append files
that you want to filter out of the build process.
Usually, this is not necessary.
However, on rare occasions where you might want to use a
layer but exclude parts that are causing problems, such
as introducing a different version of a recipe, you can
use
BBMASK
to exclude the recipe.
It is possible to filter or mask out .bb
and
.bbappend
files.
You can do this by providing an expression with the
BBMASK
variable.
Here is one example:
BBMASK = "/meta-mymachine/recipes-maybe/"
Here, all .bb
and
.bbappend
files in the directory that match
the expression are ignored during the build process.
