Hei hei,
sorry for digging up this old discussion, but I kind of want to use this
approach and … see below.

Currently trying to build recent U-Boot for i.MX8 and i.MX9 based boards which
require additional firmware. However I still want to build OOT to keep my
source tree clean, especially when building with an external tree (after
`ptxdist local-src u-boot $HOME/src/u-boot`).
Now U-Boot needs those binaries in the build tree, it does not work using this
nice inject mechanism putting it in the source tree.

Here <PKG>_DIR is assigned to pkg_source which makes the source dir the target
folder.
Did anyone already think of how to extend this approach to be more flexible
for the target folder? Maybe even without damaging existing use cases?
Maybe adding a new optional variable <PKG>_INJECT_DEST which defaults to
<PKG>_DIR and can be overridden?
