Currently I am managing my custom packages in `~/texmf`, and it is going very well.
However, due to some reasons, I want to have many TEXMF trees in my system. For example, I want `/path/to/another/texmf` or `/path/to/another/different/texmf` to be treated by `kpsewhich` and TeX the same way `~/texmf` is being treated.
Is it possible?
I am using TeX Live 2019 in Windows 10 (but feel free to suggest Unix solutions :)).

If you're running TeXlive you can add a folder to the list of folders to be searched (without needing to be indexed, so like the `$TEXMFHOME`) by issuing the following command (this will be permanent, should be run as root -- on \*nix that is, no idea about Windows):
```sh
tlmgr conf auxtrees add /path/to/folder
```
A folder added this way might be removed using
```sh
tlmgr conf auxtrees remove /path/to/folder
```

Additionally the readme of https://github.com/pgf-tikz/pgf states the following possibility (but I never tried that one) for an inclusion for the current shell session (for example to test building the pgfmanual, this replaces your `$TEXMFHOME`):
```sh
tlmgr init-usertree --usertree <folder>
export TEXMFHOME=`realpath <folder>`
```

I think I figured it out.
When looking at `/path/to/texlive/2019/texmf-dist/web2c/texmf.cnf`, I found this line:
```none
TEXMF = {$TEXMFAUXTREES$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFDIST}
```
So I just add the following lines to my custom `texmf.cnf` file (`/path/to/texlive/2019/texmf.cnf`):
```
TEXMFCUSTOMONE = /path/to/texmf/first
TEXMFCUSTOMTWO = /path/to/texmf/second
TEXMFCUSTOMTHREE = /path/to/texmf/third
%...
TEXMF = {$TEXMFAUXTREES$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFDIST,$TEXMFCUSTOMONE,$TEXMFCUSTOMTWO,$TEXMFCUSTOMTHREE}
```
Now if I put a `.sty` file in `/path/to/texmf/first/tex/latex/a`, it works:
```
$ kpsewhich a.sty
/path/to/texmf/first/tex/latex/a/a.sty
```
However, I am not sure if I have completed everything. Is there anything I need to do now?
