CPM.cmake VS imgui

I like to pin GitHub dependencies using a commit hash, instead of a tag. You need a recent CPM.cmake file in your project for CPM to work.

C++20 brings std::format, improving C++ developer experience for formatting strings. If you have to use older standards, though, add fmtlib to your repo. It plays well with CMake and you can use CPM to add fmtlib to your project. The library supports many Rust format macro features, and makes code far cleaner when you need to do string interpolation with variables.

This is true for almost all projects but things are getting better. I use CPM for a couple of years now and get the experience desired

Yes, i found vcpkg terrible and FetchContent usually works way better. An amazing project is https://github.com/cpm-cmake/CPM.cmake, which automates FetchContent and makes dependencies mostly hassle free.

There's two completely different aspects to your question. 1) How to manage libraries in c++ without dying from cringe? I'd suggest you use cmake as the build system and grab library sources directly from GitHub using this tool: https://github.com/cpm-cmake/CPM.cmake 2) How to get apps that run under WSL to display windows-native windows? I'm not sure, but it's probably this: https://github.com/microsoft/wslg

I personally like to use something called CPMCmake for smaller personal projects, just because it has 0 requirements on the person that wants to use your project, they don't have to setup anything on their end, the only requirement is to have Cmake.

I personally would thoroughly recommend CPM. It's a CMake plugin which you install as a script in your CMake project and you can then use its function CPMFindPackage(), which basically wraps find_package() and ExternalProject() to use the former if the package is installed on the machine, or downloads it and builds it in-tree using the latter if not.

At first, I wanted to install it using Vcpkg but I ended up using CPM.cmake instead. Why? Because with Vcpkg on some platform it is messing up the config and choose a version of Python used in Vcpkg instead of the one I wanted to use. It is not that hard to fix, but why bother when I can install the library in one line with CPM.cmake

set(CPM_DOWNLOAD_LOCATION ${CMAKE_BINARY_DIR}/CPM.cmake) file(DOWNLOAD https://github.com/cpm-cmake/CPM.cmake/releases/latest/download/cpm.cmake ${CPM_DOWNLOAD_LOCATION}) include(${CPM_DOWNLOAD_LOCATION})

We're using vcpkg - tried conan previously. I think both are good, but both of them have their own flaws. You can also go with something like https://github.com/cpm-cmake/CPM.cmake if you just want something quick for a small project.

Immediate mode is a fuzzy concept, as witnessed by this writeup: https://github.com/ocornut/imgui/wiki/About-the-IMGUI-paradi...

It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:

https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...

DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.

I understand whats happening, but you know sometimes I just want to display a fucking image.

ImGui is engine/GPU agnostic

Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.

AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

They use a Dear ImGui, a C++ GUI library.

Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."

https://github.com/ocornut/imgui/wiki/Multi-Viewports

This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
