Compiling and Installing

Compilation Dependencies

Ubuntu and based distros (Mint, Pop!_OS, etc.)

sudo apt install build-essential cmake git libgl1-mesa-dev libxkbcommon-dev qt6-base-dev qt6-wayland smartmontools

Fedora and derivatives (Nobara Project, etc.)

sudo dnf install cmake git mesa-libGL-devel libxkbcommon-devel qt6-qtbase-devel qt6-qtwayland-devel smartmontools

Compilation Steps

First you will need to clone the repository and cd inside

git clone https://github.com/edisionnano/QDiskInfo.git && cd QDiskInfo

Then you must create a build directory and cd inside

mkdir build && cd build

After that use CMake to setup the project, Qt version can also be set to 5 (for example for Ubuntu)

cmake .. -DCMAKE_BUILD_TYPE:STRING=MinSizeRel -DQT_VERSION_MAJOR=6

And finally compile the project with all the threads

make -j$(nproc)

This will create a QDiskInfo binary on the build directory but you can also install it using

sudo make install

Using CrystalDiskInfo Anime Themes

The process is similar to the one above with a few changes:
First you must download the edition of CrystalDiskInfo you want (Aoi for example) in ZIP format from here, from this archive you shall copy the light and dark backgrounds as well as the good, caution, bad, unknown icons to dist/theme with the same name as the templates there.
Once you do that compile like above but when running CMake do this instead:

cmake .. -DCMAKE_BUILD_TYPE:STRING=MinSizeRel -DQT_VERSION_MAJOR=6 -DINCLUDE_OPTIONAL_RESOURCES=ON -DCHARACTER_IS_RIGHT=ON

Regarding the -DCHARACTER_IS_RIGHT set it to ON for themes where the character is right (like Aoi) or OFF for most other themes.
