Force CMake to use MSVC with Ninja

I am trying to compile aseprite on 64-bit Windows and using CMake and Ninja to compile it

When I am running CMake I see that it is using MINGW64 to make the build files, even though it is mentioned that MinGW is not supported. I tried writing -DCMAKE_IGNORE_PATH=C:\MinGW\bin but it seemed to ignore it, and when running ninja aseprite I get an error

GENERATION:

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLAF_BACKEND=skia -DSKIA_DIR=C:\deps\skia -DSKIA_LIBRARY_DIR=C:\deps\skia\out\Release-x64 -DCMAKE_IGNORE_PATH=C:\mingw64\bin -G Ninja ..

I have checked and all dependencies exist

ERROR:

I saw an issue on github, and the solution was to change from GCC to MSVC, but its not mentioned how to force MSVC for the generation process. When I delete mingw64 from PATH, it still somehow finds it, if I remove the folder it throws an error that GCC was not found.

How do I force MSVC on CMake?

I believe cmake -G Ninja needs to be cmake -GNinja or cmake -G "Ninja". - Jesper Juhl
@JesperJuhl it works anyways, it says that build files were written. The error occurs when I write ninja aseprite - frogstair

I fixed this by changing the environment variable CC to cl

set CC=cl
