Hello,

I just installed Clang-LLVM-10.0.0 for x64 Windows and tried to compile a 
simple program (pasted below) using "clang++.exe hello.cpp" but got an error 
stating; clang++: warning: unable to find a Visual Studio installation; try 
running Clang from a developer command prompt [-Wmsvc-not-found]
.\hello.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>
         ^~~~~~~~~~
1 error generated.

//-- simple program below --
#include <iostream>

using namespace std;

int main(int argc, char* argv[]) {
        if(argc < 2) {
                cout << "Hello, world!" << endl;
        } else {
                cout << "Hello, " << argv[1] << "!" << endl;
        }

        return 0;
}

Is there any way to use Clang-LLVM without having to install Visual Studio 
(which is a 7.5GB download)?

Thanks,

~Mayuresh
