Simple C++ Project

Simple C++ project with CMake build system + CPM as package manager. This project included with separated apps and libraries for example.

CPM (CPM.cmake) is a cross-platform CMake script that adds dependency management capabilities to CMake. Readmore https://github.com/cpm-cmake/CPM.cmake

This project also has been preloaded with libraries:

1. spdlog https://github.com/gabime/spdlog
2. fmt https://github.com/fmtlib/fmt

How to use

1. Install CMake, minimum version 3.20

2. Just to run defined command (optional)

3. Build app by running this command:

   cmake -S . -B build -G "Ninja Multi-Config" # or use `just cmake`
   
   # to build debug app:
   cmake --build build --config Debug # or use `just build_debug`
   
   # to build release app:
   cmake --build build --config Release # or use `just build_release`

4. To run app:

   # to run debug app
   ./build/bin/Debug/example # or use `just run_debug example`
   
   # to run release app
   ./build/bin/Release/example # or use `just run_release example`

all command can be found inside justfile

How To Add Dependency (CPM)

Dependency can be added in CMakeLists.txt or organize it in cmake/dependnecies.cmake (recommended).

Example:

CPMAddPackage("gh:fmtlib/fmt#11.1.3")

# or

CPMAddPackage(
  GITHUB_REPOSITORY gabime/spdlog
  VERSION 1.15.2
  OPTIONS "SPDLOG_FMT_EXTERNAL 1"
)

Compile Command

The CMake also generate compile_commands.json for LSP.

   cmake -S . -B build  # or use `just cmake`

File compile_commands.json can be found in build/ directory
