# workonsrc.bbclass enables use of an existing source tree, usually workon to
# the build system to build a piece of software rather than the usual fetch/unpack/patch
# process.
#
# To use, add workonsrc to the global inherit and set WORKONSRC to point at the
# directory you want to use containing the sources e.g. from local.conf for a recipe
# called "myrecipe" you would do:
#
# INHERIT += "workonsrc"
# WORKONSRC_pn-myrecipe = "/path/to/my/source/tree"
#
# In order to make this class work for both target and native versions (or with
# multilibs/cross or other BBCLASSEXTEND variants), B is set to point to a separate
# directory under the work directory (split source and build directories). This is
# the default, but the build directory can be set to the source directory if
# circumstances dictate by setting WORKONSRC_BUILD to the same value, e.g.:
#
# WORKONSRC_BUILD_pn-myrecipe = "/path/to/my/source/tree"
#
