It's just a command and controll server. It's awfull. Don't use it.

Build agent

On windows there will probably be a project file created for visual studio

cmake --build build

Or if you are crosscompiling then:

cmake --build build -DCMAKE_TOOLCHAIN_FILE=../crosscompile.cmake

And then on linux:

cd build
make -j

Build teamserver

go build -o teamserver ./cmd/main.go
