I'm trying to build my main.tex that includes a standalone pic.pdf. Special is, that pic.pdf needs to be built by latexmk (via the -use-make flag) while actually building main.tex.

The problem appears to be, that the latexmk invocation for main.tex stops after building pic.pdf through make. Log output states due to errors, though pic.pdf was built fine before.

Here is my MWE:

Makefile

main.pdf: main.tex
    latexmk -interaction=nonstopmode -pdf -use-make -M -MP -MF $(@:.pdf=.d) $<

pic.pdf: pic.tex
    latexmk -interaction=nonstopmode -pdf -M -MP -MF $(@:.pdf=.d) $<

-include main.d
-include pic.d

clean:
    find . -not -name "*.tex" -not -name Makefile -delete

main.tex:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}[h]\includegraphics{pic.pdf}\end{figure}
\end{document}

pic.tex:

\documentclass[crop]{standalone}
\usepackage{tikz}
\begin{document}
 \tikz \fill [orange] (0,0) rectangle (6,2);
\end{document}

To reproduce the problem, run

make clean && make

This stops with an error after building main.pdf and pic.pdf, but should actually just re-build main.pdf once again and everything should be fine.

Question: How can I configure latexmk to re-try building main.pdf after its requirement pic.pdf has (successfully) been generated?

For the reference, here my log output (manually shortened; omitted stuff indicated via [...]):

In case of interest, I'm using the following versions of contributing components:

latexmk:  Latexmk, John Collins, 19 Jan. 2017. Version 4.52c
pdflatex: pdfTeX 3.14159265-2.6-1.40.18 (TeX Live 2017/TeX Live for SUSE Linux)
make:     GNU Make 4.2.1

The problem seems to be that latexmk thinks the error 

Package pdftex.def Error: File `pic.pdf' not found.

is non recoverable. To bypass that, we can include pic.pdf iff it exists and print a warning for latexmk otherwise. More precisely, after changing the main.tex in the MWE to:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}[h]
 \IfFileExists{pic.pdf}{\includegraphics{pic.pdf}}{\typeout{No file pic.pdf.}}
\end{figure}
\end{document}

the problem is resolved: make clean && make finishes without errors after building main.pdf twice. In the first round, the file doesn't yet exist, but we still compile fine and only print a message on the missing file.

(In the real world you will probably define a new command that handles the \IfFileExists.)

Idea taken from this related question on \input (instead of \includegraphics). All credit to @JohnCollins.
