I see that having download links to all the dependencies is useful in particular when trying to build the Berkeley DB part of Bitcoin Core yourself, because it's so ancient that newer versions of BDB are incompatible with anything bitcoin-related, at least from the projects I try odd to compile, and will generate linking errors during compilation.
So I thought it would be useful to have separate instructions for building BDB by itself on Linux.
[1] Yes, you absolutely have to build Berkeley DB in this folder, otherwise it will spit out an error like this:
[2] It installs it to /usr/local so that it does not conflict with any system-wise installation of Berkeley DB.
Now to compile stuff with it just pass -I/usr/local/include -L/usr/local/lib -ldb to gcc. And then you run your program like this:
Or
The latter is useful to put in your .bash_profile or .bashrc so that it's automatically set for you at login.
Failing to set LD_LIBRARY_PATH will give you the following error when you start your program:

configure: error: Berkeley DB should not be built in the top-level or "dist" directories. Change directory to the build_unix directory and run ../dist/configure from there.

Thank you very much for the feedback!
As you can see in the title, I tried to specify that it is for Windows systems and not separately for Bitcoin, but any other type of currency that follows the same compilation line of the tutorial provided by our friend nitrogenetics.
Note that I also informed that the dependencies can be different depending on the project you are looking to work on, a lot can change in different versions of projects. In any case, the dependencies and versions must be the same as those described in the project documentation you are looking to use.
