Quick install fails on Solus (Package opencv4 was not found in the pkg-config search path.)

[efugier]

• Solus 3.9999
• run normal quick install procedure for go cv
• final make install output is:

Package opencv4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv4.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv4' found

Solutions listed in #57 do not work because the Solus' opencv version is 3.4, but installing opencv-devel seems to fix the "not found" part of the problem.

Installing opencv from source does not work either.

The "-dev" or "devel" thing appears to be missing when installing through your procedure or opencv's, and I can't find a way to do it manually other than install opencv-devel which is not recent enough in my case.

Regardless of my personal case, this is supposed to be self-sufficient, and it's not (at least on Solus) !
