ninja: build stopped: subcommand failed.



Source file was:
#include <stdatomic.h>
int main () { 
	atomic_int_least32_t value = 0;
	atomic_fetch_add (&value, 1); 
	return 0; 
}

I am on Windows 10 Home, executing the build command from MSYS2 MinGW x64. Some digging around shows that basically nothing from vstgui4 is building, which seems to be what is causing the fail.

which version of cmake do you use? did you try to update it?
