If you want to show us how you'd refactor his code from a maintainability standpoint into a proper setup, I think that would be extremely useful. Too often we focus on refactor for performance, but in this case, just not having to edit two files for one change is a great lesson to impart.

Separating apps and libraries into corresponding subdirectories can help with organization and reusability

From what I understand, CMake also generates projects for Visual Studio. In this case, it's cross-platform, creating a Makefile on Unix and a Visual Studio project on Windows

@heavymetalmixer91

Yeah, CMake can produce files for several IDEs/editors and cross-platform, that's why it's so popular.

@maxmustermann3938

More than that. Several IDEs just support CMake out of the box (i.e. they run the necessary CMake command for the given build environment internally and support the entire thing in the IDE, even helping you when you add files, no need to run any batch or shell scripts...). On top of that, you got things like vcpkg which is a package manager centered around CMake (and MSBuild) that can help you a lot. Got some project with a CMakeLists.txt? Just open the folder in VS Code (with proper extensions), Visual Studio, CLion, ... that's all. A bunch of years ago, we we're still using some batch script or shell script that would generate solution files or makefiles, but then support was added in Visual Studio, CLion also supported it (i think even before VS) and then VS Code came along with its platforms which can be used as an IDE supporting CMake projects on windows, linux and mac. Since CMake is used so widely, it's trivial to get any CMake library setup to be able to be used in your project, even if it is not contained in your package manager.

Nice to see a video about project setup. But please people, prefer out-of-source builds! CMake supports and recommends it, I hope Premake also. While having your generated project files sitting next to your code sounds like a good idea, it will bring more problems than solutions in the future. Build into a separate folder, you can even have different folders for different build types or experiments. Deleting a single folder ensures a clean state of the project. in CMake: git clone cd mkdir build cd build cmake .. cmake --build .

@michaelterekhov1678

Absolutely! I think that in case of crossplatform development and in case you want to make such components management the best solution is git-modules and cmake. cmake works on any platform you like, it can generate *.sln file for Windows and xcodeproject in case of MacOS. Cmake has special folders management called include(GNUInstallDirs). And it is much more pleasant then pure MAKE of unix

Agree. Now that vcpkg has manifests, it fixes a giant hole that previously you'd have needed conan for. I'd been using vcpkg instead of conan even before that, just preferred it, but I ran into issues where I'd check out an old repo on a new vcpkg install and the newer package versions broke it. Now you can specify dependencies and version requirements in a manifest and use it like a reasonable package manager (ofc, conan has had that long before).

Thanks a lots from vietnam, your videos is so detail and easy to understand

Hay not sure if have seen this, but have you had a look at the build chain and tooling that is coming with zig to compile/cross-compile/manage dependencies for C/C++ projects? Think it might make life easier in some way for you.

Could you make a video about how to design a library? or how to set up a library? BTW love your videos, keep going

Could you make a video on turning cmake libraries to premake and if there are some automated tools.

Just a point of clarity on build systems: Both Premake and CMake are build system generators - all of the benefits that you enumerated for Premake apply to CMake as well. It would be good to see how you pull in dependencies to this template as well - do you do it manually or with a package manager?

The project in this video uses SFML and IMGui, and I think he added them manually.

You are doing a great job. I have learnt a lot from your videos. Pls make a series on CONAN package manager.

Couple of items. Even watching here, we see repeated common blocks in your premake lua files (configurations, preprocessor defines, compiler settings, directory patterns, architectures...). I've found it very useful having a file "common.lua" and executing that using "dofile" in each premake file. Don't Repeat Yourself is a good goal. Second, is imGUI actually embedded in the source? Might be good time to discuss git submodules.

How would I add sfml to the project template? Where would I add the necessary dll, lib files ect?

Omfg i needed this so bad im so bad at being organized like most of us programers that would rather think than organize

I think I tried conan before, if I remember right, it has a CMake integration too. I myself use vcpkg (both with CMake, as well as in situations where I am working with visual studio solutions, since it works there too). VCPKG has all the stuff you'd need to OpenGL too, including imgui (with configurable bindings, i.e. imgui[glfw-binding,opengl3-binding] if you want opengl plus glfw setup, which is what I always use). You can also use it as a submodule if you want, since it is itself just compiled with C++, it's easy to set even that up cross-platform in your CMake script so that someone doesn't even have to manually install it. vcpkg also recently added manifests, which was much needed (i.e., specifying dependencies in a vcpkg.json file in your project, along with version requirements, just like conan does it)

another really great tool is xmake, which also uses lua but it's kind of its own build system as opposed to a metabuild system

You know the video is about to slap when the thumbnail has The Cherno with that Oppenheimer face.

This is an awsome video.

I am taking notes.

So i was just setting up this template to be used with glfw where i wanted to wrap glfw in the core and only expose a non glfw specific api for the app. One thing i noticed was i had to include the glfw lib as an include of app as well if i included my wrapper even know the wrapper doesn't expose any glfw specific types. Seemingly i should be able to compile glfw into my "core" lib then only include it in the app project right...? Did i set something up wrong or is this not the case?

This looks good. However, Can you create a template using CMake? that will be helpful too

Can you do one on cmake too?

Depending on what platforms you ship to, using Visual Studio solutions can be fine. You don‘t have to use a build system if you don‘t need it. Commercial games and engines have been shipped using just native IDE solutions. Setting up a buildsystem however is a lot more important for open source software, where you probably want to run it in as many places as possible. So consider if you need it, what benefits it brings, and if it‘s right for you.

I have the same question. Modern CMake is easy (with the correct docs) and straight forward: target_something. Precompiled headers, done. Unity builds, done. Packages, done (conan or Fetch Content). Pre or post build scripts, done.

Any integration with linux IDE/Editors? Ive been looking for an alternative to msbuild since ive migrated to linux. Been using CMake and so far it's okay

let's go

7:22 fellow chatgpt user :)

I used to be on the Premake train. But the integration with IDEs that CMake has just does not compare at all to what Premake offers. Premake is certainly easier for a primarily Visual Studio user for sure. But if I want to develop on Linux and not just "build" on Linux for instance, I want CMake. I'm not some die hard VIM user, I want to be able to use a graphical IDE anywhere.

That's nice, I refuse to use modern IDE's still because I'm insane, so I've only really written my own Makefiles so far. Ah the pain. I think I'm going to stop making my own Makefiles now.

There is no real “one size fits all” solution for apps. Not everything needs some supporting core library and a whole build system

Can someone tell, why using premake is better than CMake? For me it seems like almost all libraries are using CMake nowadays.

how do you start adding your own files? i right-clicked the Core project in the Solution Explorer, and i added one new file in the same directory as Core.cpp and Core.h its called Logger.h i included it in Core.cpp like so; #include DEVELOPING ANYWHERE ELSE this would be fine, but because Visual Studio is beyond annoying, it will not include it and is throwing errors that it cannot find a file name "Logger.h" after pressing F5 i want to throw Visual Studio into a volcano every time i use it

The way I figured out: 1. Right-click the "Core" project -> Choose "Add" -> "New Class..." 2. Then type the name of my class "Foo" or something. 3. Add "Source/Core" to the front of both the Foo.h and Foo.cpp file path input fields. DONT use your file browser to choose the "{Solution}/Core/Source/Core" folder. It does not work. Because... reasons? By default the files just go into the root of that solution, again because... reasons? 4. Click "Ok". 5. Right click "Core" solution again and click "Build". 6. You _should_ then be able to `#include "Core/Foo.h"` in "App.cpp", build it, run it, etc. I dOn'T kNoW wHy YoU'rE hAvInG tRoUbLe? \sarcasm incase not obvious.
