Feather is a language-agnostic, universal user interface library.

Feather uses cmake to build, and utilizes nix flakes on NixOS, or the vcpkg build system on all other operating systems.

Feather maintains a fork of vcpkg (this may be turned into an overlay in the future). Clone the git repository from https://github.com/Fundament-Software/vcpkg into a folder with enough space to hold a bunch of compiled binaries, and run bootstrap-vcpkg.bat (for windows) or bootstrap-vcpkg.sh (for other OSes). Once the script completes, run vcpkg install glfw3:x64-windows-static (on windows, start with .\vcpkg.exe) and follow any instructions that pop up.

Next, clone the featherGUI repo, if you haven't already. Inside the root directory of the repo, create a build directory and open it. Inside the empty build directory, run the cmake command that is appropriate for your platform, being sure to replace <ROOT_VCPKG_FOLDER> with the folder you cloned vcpkg into, and adding any additional options you would like.

cmake .. -DCMAKE_TOOLCHAIN_FILE=<ROOT_VCPKG_FOLDER>\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static

If you don't have cmake installed on your system, you can use the version vcpkg installed:

<ROOT_VCPKG_FOLDER>\downloads\tools\cmake-<LATEST_CMAKE_VERSION>-windows\cmake-<LATEST_CMAKE_VERSION>-windows-x86\bin\cmake.exe .. -DCMAKE_TOOLCHAIN_FILE=<ROOT_VCPKG_FOLDER>/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static

cmake .. -DCMAKE_TOOLCHAIN_FILE=<ROOT_VCPKG_FOLDER>/scripts/buildsystems/vcpkg.cmake

If you don't have cmake installed on your system, you can use the version vcpkg installed:

<ROOT_VCPKG_FOLDER>/downloads/tools/<CMAKE_PATH_FOR_YOUR_PLATFORM>/bin/cmake .. -DCMAKE_TOOLCHAIN_FILE=<ROOT_VCPKG_FOLDER>/scripts/buildsystems/vcpkg.cmake

Ensure that you have enabled flake support in your configuration.nix file (or equivilent):

nix.package = pkgs.nixFlakes;
nix.extraOptions = ''
  experimental-features = nix-command flakes
'';

Clone the featherGUI repository, if you haven't already, then run nix build inside the root directory.
