libarpack.so is present in arpack (from community repo) but there isn’t a library for arpack++. Can I copy the library “libarpack.so” from arpack to the folder where arpack++ is installed? So this way I just need to change his name and this wont happen:
-- Found Arpack++ lib: ARPACKPP_LIB-NOTFOUND
pkgfile libarpack++.so shows there is not package actually using this library
How can I make libraries given hearder files (.h)?
After I installed arpack++ from AUR I copied the missing files (.so and .a files) from ubuntu repo (I got them using a container) into a path /usr/lib
Im not sure it will work
FindArpackPP.make

Looks like arpack++ does not contain a library by default. There is also arpackpp in the AUR, it matches the Debian version, but it provides just the headers. If you compile a application, this should be enough.
You might want to check what source the Debian project uses and try to compile it yourself.
