Building a Discord Bot using CMake/UNIX

1. Toolchain

Before compiling, you will need to install cmake on your system. To be sure that cmake is installed, you can type the following command:

$ cmake --version
cmake version 3.20.4

2. Create a CMake project

In an empty directory, create the following files and directories:

- your_project/
    |-- libs/
    |-- src/
        |-- main.cpp
    |-- CMakeLists.txt

In the libs/ directory, clone D++ with: git clone https://github.com/brainboxdotcc/DPP.git

3. Configure CMake

Here is an example CMake configuration, adapt it according to your needs:

# minimum CMake version required
cmake_minimum_required(VERSION 3.15)
# Project name, version and description
project(discord-bot VERSION 1.0 DESCRIPTION "A discord bot")
 
# Add DPP as dependency
add_subdirectory(libs/DPP)
# You can also add any other libs you want to use
 
# Create an executable
add_executable(${PROJECT_NAME}
    src/main.cpp
    # your other files...
)
 
# Linking libraries
target_link_libraries(${PROJECT_NAME}
    dpp
    # Add any other libs you want to use here
)
 
# Specify includes
target_include_directories(${PROJECT_NAME} PRIVATE
    libs/DPP/include
    # Remember to add the include directories of any other libraries too
)
 
# Set C++ version
set_target_properties(${PROJECT_NAME} PROPERTIES
    CXX_STANDARD 17
    CXX_STANDARD_REQUIRED ON
)

Your project directory should look like this:

- your_project/
    |-- libs/
        |-- DPP
    |-- src/
        |-- main.cpp
    |-- CMakeLists.txt

Have fun!
