[PATCH] Generate .lib files on PE platforms

Ulf Hermann ulf.hermann@qt.io
Wed May 3 11:27:00 GMT 2017


MSVC needs them to link against .dll files. gcc can do without, so we
only need to do this when actually installing the files. There is a way
to generate .lib files with dlltool, but most of the time MSVC won't
cleanly link against the result, so we rather use lib.exe here.
