In the past (TeXworks v0.4.0 r.759 / MikTeX 2.9) I used the following texify option to inform texify about the location of additional input files:
This also caused bibtex to find extra .bib files.
Now, with version 0.4.6 (MiKTeX 2.9 64-bit), the same texify option only lets the latex pass find additional styles and other input files. There is a LaTeX Warning complaining about "Empty 'thebibliography' environment on input line XX" and bibtex reports (in the .blg file): "I couldn't open database file XXX".
I can use -include-directory=C:\TexInputFiles\ for pdfLaTeX and for BibTeX individually and then invoking the passes manually delivers the desired result, i.e., bibtex finds the .bib files.
However, it seems that texify used to pass on the "--tex-option=" value to bibtex as well as latex but only does so now for latex. Is that possible?
Is there any chance to fix that or is there a workaround?
I tried setting the environment variables BIBINPUTS and TEXINPUTS to C:\TexInputFiles\ (and C:\TexInputFiles\) (in System | Environment Variables | System variables) but under Windows environment variables always seem to be ignored.
