Hi,

Here are patches adding qcustomplot and wfview.

For some reason upstream puts the sources and the makefile of
qcustomplot in different tarballs. I put the archive with the makefile
as native input using ",(origin (method url-fetch )...)".
Would you do it differently?

These two packages also have custom 'install' phases because the default
ones didn't install everything, or tried to install using a custom
script with hard-coded "/usr/..." paths.
