pdfTeX - get rid of pdf inclusion version warnings

When you include pdf-images in your LaTeX document and get this kind of warnings:

pdfTeX warning: pdflatex (file ./fig/fig_FooBar.pdf): PDF inclusion: found PDF version <1.5>, but at most version <1.4> allowed [...]

Then give pdfTeX this command:

\pdfminorversion=5

This way pdfTeX builds the document with pdf Version 1.5 instead of 1.4.
Before:

> file document.pdf
document.pdf: PDF document, version 1.4

After:

> file document.pdf
document.pdf: PDF document, version 1.5

and no more warnings.

Thanks to Mads Darø, found the solution in his blog:
