To install the rust toolchain for building the project go to rust-lang.org and follow the instructions.
Protobuf's CLI (protoc) is required to build this project as it is used to auto-generate rust code based on the protobuf of the underlying API which communicates with Keymapp.
Install using winget:
winget install protobuf
In order for tonic-build to build, it needs to know the path of protoc. Therefore, we need to add the executable path to an environment variable using powershell:
[Environment]::SetEnvironmentVariable('PROTOC', '%USERPROFILE%\AppData\Local\Microsoft\WinGet\Packages\Google.Protobuf_Microsoft.Winget.Source_8wekyb3d8bbwe\bin\protoc.exe', 'User')For Linux & MacOS you can follow Google's installation instructions: grpc.io
