[Lazarus] Issues with creating packages that have dependencies with other packages

[Krzysztof]

Hi,

I'm author and maintainer of BGRA Controls package. This package must
have installed BGRA Bitmap package. I'm wondering, can I somehow
include BGRA Bitmap into BGRA Controls package? I want this solution
because then I know that everything should work (user could have some
old version of BGRA Bitmap) My doubts:

1. Is the license permits it? Both packages are on LGPL
2. How to do it? Just copy source of BGRA Bitmap to BGRAControls
directory and add path to this folder in package options?
3. How to Lazarus behave if user have installed some other version of
BGRA Bitmap and try to install BGRA Controls with BGRA Bitmap
included? Which version of BGRA Bitmap my controls use? Local or
global?
4. Is this good practice anyway?

Regards
