I have found a copyright statement in the documentation, that I have put
in a COPYING file.

I changed the Depends and BuildDepends in the package.

I also moved the compilation done during the installation phase to the
compilation phase. The -DHELPFILE thing is indeed normal. It seems that
the help file is included in the binary, so it's not needed to install it.
The
help in wip without it works just fine.

I contacted the developer about the licence. WIP was developped by a
scientific institution and is a free software, but there is no license
file nor
copyright statement in the source code. What should we do in such case
?

If you're linking against a shared library, you need to
BuildDepends on the pkg containing the headers and primary
lib/*.dylib link and Depends on the -shlibs pkg containing
the actual runtime code. So instead of:
Depends: libpng3
would be:
BuildDepends: libpng3
Depends: libpng3-shlibs

Seems like there's an awful lot of compiling happening
during the install phase. As a result of doing that, you get
a -DHELPFILE (which gets hard-coded into the wip executable)
that contains the build path instead of the runtime path.
OTOH, that helpfile does not get installed at all...

Need a file in share/doc/%n containing a copyright
statement. The README you install (via DocFiles) only
contains compile/install instructions. Perhaps use the doc/
dir in the tarball?
