Why isn't the Ultralight library built?

Question

C++ / C#

Here I am trying to compile the Ultralight Bible, on Windows:
I download the archive , unpack it of course.
Then in the console:

cd S:\Ultralight-1.2.1\Ultralight-1.2.1
cmake-gui

After that, in cmake-gui I set everything like this:

And I click Configure > Finish > Generate (all options are unchecked).
Well, I run make:
mingw32-make
I wait and get

conclusion

$ mingw32-make

Everything seems to be except for examples, but I don’t need them, it compiles.
After that, there are 4 more folders in the SDK folder, bin, lib, include, inspecror. I share the last rhinestone.
There are 4 files in the lib:
AppCore.lib
Ultralight.lib
UltralightCore.lib
WebCore.lib
Here is the catch, I need not .lib but .a files, I use MinGW-W64.
Okay, maybe he supports them,

spoiler

походу нет

.
I rename them to:
libAppCore.lib.a
libUltralight.lib.a
libUltralightCore.lib.a
libWebCore.lib.a
What the linker could find, otherwise it doesn’t work with the -l command
Okay, I copy the bin folders (there are 4 dlls with the same names ), include and lib in
bin - S:\MinGW\bin
include/lib - S:\MinGW\local\include -/- lib
And compile

example

#include <AppCore/App.h>
#include <AppCore/Window.h>
#include <AppCore/Overlay.h>
#include <AppCore/JSHelpers.h>
using namespace ultralight;
class UltralightMain {
  RefPtr<Overlay> overlay;
public:
  UltralightMain(Ref<Window> win) {
    overlay = Overlay::Create(win, win->width(), win->height(), 0, 0);
    overlay->view()->LoadURL("file:///main_window.html");
  }
virtual ~UltralightMain() {}
}
int main() {
auto app = App::Create();
auto window = Window::Create(app->main_monitor(), 450, 700, false,
kWindowFlags_Titled);
window->SetTitle("Hi Ultralight here!");
app->set_window(window);
UltralightMain my_app(window);
app->Run();

  return 0;
}

command:

g++ main.cpp -o main -IS:\MinGW\local\include -LS:\MinGW\local\lib -lAppCore.lib -lUltralightCore.lib -lUltralight.lib -lAppCore.lib

And I get

this

Maybe g++ doesn't support .lib? Then how to convert .lib to .a?
