[Debian-astro-maintainers] Bug#943603:

[Cyril Richard]

I don't understand why this bug has come back.

The error is here:

checking how to run the C++ preprocessor... g++ -E
checking whether g++ supports C++11 features by default... yes
checking for OPENCV... no
checking for OPENCV... no
checking for OPENCV... no
configure: error: opencv not found. Not using some image processing.
	tail -v -n \+0 config.log
==> config.log <==


because opencv 4.1.2 dropped the pkg-config file.
But opencv 4.1.2+dfsg-4 reintroduced the file (#942562) and now I can
compile with pbuilder and opencv 4.1.2 without any issue.
