Hello.

How fix this?

[ogoffart]

/bigobj is a MSVC option.
It is set there:

slint/api/cpp/CMakeLists.txt

Lines 151 to 152 in ddeb824

	if (MSVC)
	target_compile_options(Slint INTERFACE /bigobj)

But from the error, it looks like you're using mingw. How can the option be set since we have a if (MSVC)

How did you configure the project? Why do cmake believe you are using msvc but then runs mingw?
