Re: Curl as static library with dependencies

The msys2 project provides up-to-date mingw-w64 builds for all these
libraries, shared and static. This is what everyone uses to build with
mingw-w64. Just download msys2 and run:

   pacman -S mingw-w64-{i686,x86_64}-curl

Alternatively you can download the msys2 builds manually from:
http://repo.msys2.org/mingw/

You can then get the correct build and linker flags using e.g.:

  pkg-config --cflags --static libcurl
  pkg-config --libs --static libcurl

The main gotcha is that you need to compile your application that
links against libcurl with -DCURL_STATICLIB to support static linking.
