win32/generate-msvc.mak: Add rules for gtk30[-properties].pot
Hi,
This attempts to support building gtk30.pot
and gtk30-properties.pot
with the NMake Makefiles, which will require xgettext.exe
from Cygwin or msys2, or a patched version for Visual Studio. This will help to support builds from GIT checkouts better.
With blessings, thank you!
