I‘m a visual studio user under win11. Now I’d like compile the source code downloaded from github and further generate the vs 2022 project with Cmake 3.23.0-rc1(gui). But I met some mistakes and could not find the way out.  
Ps:  
**Cmakelist.txt** \*\*\*\*\*\*\*\*\*\*\*  
cmake\_minimum\_required(VERSION 3.7)  
project(GROOPS LANGUAGES CXX Fortran)

set(CMAKE\_CXX\_STANDARD 14)  
set(CMAKE\_Fortran\_FLAGS “-std=legacy”)  
include\_directories(${PROJECT\_SOURCE\_DIR})  
include(sourcesCXX.txt)  
include(sourcesF77.txt)  
include(sourcesF90.txt)  
add\_library(groopscore OBJECT ${SOURCES})

Error:

Actually I know little about Cmake, could some tell me what should I do to solve it?(I’d like to generate a vs project)  
Many thanks!

I don’t think Visual Studio supports Fortran in any way other than through the Intel compiler. You’ll need to use `Ninja` or a `Makefiles` generator to use `gfortran` on Windows.
