Thanks a lot for your port in OpenCFU to latest OpenCV.  Its probably
very valuable.  I've applied the patch in Salsa[1].
Unfortunately I'm still struck with the configure step:

...
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for OPENCV... no
configure: error: OpenCV not found. Have you installed the library (devel version)
	tail -v -n \+0 config.log
...


Regarding the hint of Samuel Thibault:  Yes there is 

# cat ./usr/lib/x86_64-linux-gnu/pkgconfig/opencv4.pc
# Package Information for pkg-config

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib/x86_64-linux-gnu
includedir_old=${prefix}/include/opencv4/opencv
includedir_new=${prefix}/include/opencv4

in my pbuilder chroot - but this somehow does not help :-(


Kind regards
