Compiling and Installing

Linux

To compile and install you will need the GEGL header files (libgegl-dev on
Debian based distributions or gegl on Arch Linux) and meson (meson on
most distributions).

meson setup --buildtype=release build
ninja -C build

If you have an older version of gegl you may need to copy to ~/.local/share/gegl-0.3/plug-ins
instead (on Ubuntu 18.04 for example).

Windows

The easiest way to compile this project on Windows is by using msys2. Download
and install it from here: https://www.msys2.org/

Open a msys2 terminal with C:\msys64\mingw64.exe. Run the following to
install required build dependencies:

pacman --noconfirm -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-meson mingw-w64-x86_64-gegl

Then build the same way you would on Linux:

meson setup --buildtype=release build
ninja -C build
