How do I use VCVars?

[fluddsskark]

I know this is somewhat off-topic but I don't see a lot of documentation of is besides from bruxisma's own documentation, and I tried compiling 3DMM but with no avail. I use VS2022.

What have you tried and what error message do you get?

Once you have VCVars installed, the commands from the readme should just work.

https://github.com/foone/3DMMForever#build-instructions

$ pushvc (invoke-vcvars -TargetArch x86 -HostArch AMD64)
$ cmake --preset x86:msvc:debug
$ cmake --build build

"CMake Error: Could not read presets from C:/:
File not found: C://CMakePresets.json" i get this error when i try to build it

You need to navigate to the 3DMMForever folder first.

I get the same error when I'm at the root of the C drive.

C:\
C:\
> cmake --preset x86:msvc:debug
CMake Error: Could not read presets from C:/:
File not found: C://CMakePresets.json

However, if I change my working directory to 3DMMForever, it works.

C:\
> cd "C:\Users\wjbr\src\3DMMForever"

C:\Users\wjbr\src\3DMMForever
~\src\3DMMForever
> cmake --preset x86:msvc:debug
Preset CMake variables:

  CMAKE_BUILD_TYPE="Debug"
  CMAKE_CXX_COMPILER="cl"
  CMAKE_INSTALL_PREFIX:PATH="C:/Users/wjbr/src/3DMMForever/dist"
