This project has been ported to **Qt 6.6.0**, which is not yet available in

To run this project, you will *need* to

your system, **version 6.5.0** or later.
your system, **version 6.6.0** or later.
Be sure to take note of the Qt6 installation directory, as we will need it to
correctly set our `CMAKE_PREFIX_PATH` in the next steps.
If you are building on **Windows / Mac**, consider setting
the `-DQTK_ASSIMP_NEW_INTERFACE` cmake build option.
If the build is configured with all options enabled, we can subsequently install
individual components as needed with cmake.
```bash
cmake -B build-all/ -DQTK_BUILD_GUI=ON -DQTK_INSTALL_LIBRARY=ON -DQTK_INSTALL_PLUGINS=ON
```
sudo apt update -y && sudo apt install libassimp-dev cmake build-essential git ccache libgl1-mesa-dev libglvnd-dev zlib1g-dev -y

By default, the build will not initialize Assimp as a git submodule and build
from source.
We can turn this on by setting the `-DQTK_SUBMODULES=ON` flag when running
CMake.
Building using this option will fetch and build Assimp for us, but builds will
take longer as a result.
Using `-DQTK_SUBMODULES=ON` supports providing assimp on cross-platform builds (
Windows / Mac / Linux) and may be easier
to configure.

#### Qtk GUI
Once Qt6 is installed, to build and run `qtk` on Ubuntu -
```bash
sudo apt update -y && sudo apt install libassimp-dev cmake build-essential git ccache -y
git clone https://github.com/shaunrd0/qtk
cmake -S qtk/ -B qtk/build/ -DCMAKE_PREFIX_PATH=$HOME/Qt/6.5.0/gcc_64
cmake --build qtk/build/ -j $(nproc --ignore=2)
./qtk/build/bin/qtk-main
```
By default, the build will not initialize Assimp as a git submodule and build
from source.
We can turn this on by setting the `-DQTK_UPDATE_SUBMODULES=ON` flag when
running CMake.
Building using this option will fetch and build Assimp for us, but builds will
take longer as a result.
Using `-DQTK_UPDATE_SUBMODULES=ON` supports providing assimp on cross-platform
builds (Windows / Mac / Linux) and may be easier to configure.
```bash
cmake -S qtk/ -B qtk/build/ -DQTK_UPDATE_SUBMODULES=ON -DCMAKE_PREFIX_PATH=$HOME/Qt/6.5.0/gcc_64
cmake --build qtk/build/ -j $(nproc --ignore=2)
./qtk/build/bin/qtk-main
cmake --build build-all/ --target qtk_gui -- -j $(nproc)
# Install Qtk desktop application (output removed)
# Installation prefix path must be absolute, since Qtk uses Qt deploy tools.
cmake --install build-all/ --component qtk_gui --prefix=$(pwd)/install
./install/bin/qtk_gui
```
If any errors are encountered loading plugins, we can debug plugin loading by
setting the following environment variable -
```bash
QT_DEBUG_PLUGINS=1 ./qtk-main

#### Qtk Example
If you are building on **Windows / Mac**, consider setting
the `-DASSIMP_NEW_INTERFACE` build flag.
There is a simple example of using libqtk in the [example-app/](example-app)
directory. The example can be built standalone using `find_package` or as a
target within any qtk build.
```bash
cmake -S qtk/ -B qtk/build/ -DASSIMP_NEW_INTERFACE=ON -DCMAKE_PREFIX_PATH=$HOME/Qt/6.5.0/gcc_64;/path/to/assimp/
cmake --build qtk/build/ -j $(nproc --ignore=2)
# Build the example from a configured qtk build tree
cmake --build build-all/ --target qtk_example -- -j $(nproc)
cmake --install build-all/ --component qtk_example --prefix=install
./install/bin/qtk_example
```
See the README in the [example-app/](example-app) subdirectory for instructions
on standalone builds.

To generate packages for Qtk desktop application, we should

like to bundle libqtk with the desktop application.
