Protobuf generation doesn't work on directories with spaces

[KaydemonLP]

If at any point in your directory structure you have a folder that has a space in it, the protobuf generation of messages.pb.h and messages.pb.cc

Steps to recreate:

1. Name the folder of your repository "Test Test"
2. Compile the Client or Server binaries
3. You'll see an error saying the necessary protobuf files don't exist, and in the log, the console will say that they failed to generate an output.

If the following is using source engines filesystem interface most of these issues can be fixrd by using the fixslashes function on the location itself it should allow you to even have spaces inside of a folder or file even and it will read it properly

Its in VPC code, which executes via cmd, so you can't use actual code functions
