* Synopsis

Pixelarium strives to be a batteries-included visualizer application to be used in conjunction with an external algorithm.
It can be linked e.g. against a library containing arbitrary functionally. Pixelarium can support viewing the results and result files of such a library.
It tries to be as flexible as possible.

This is still work in progress and will change significantly.

* Prerequisites

Dependencies are either submodules in the =modules= subdirectory or artifacts of the cmake build process from the =cmake= directory. This repository should therefore be cloned recursively:
#+begin_src sh
  git clone --recurse-submodules https://github.com/m-aXimilian/pixelarium.git
#+end_src

Apart from that, this project needs OpenCV installed on the host system and available for cmake's =find_package=.

* Building

Given that the prerequisites are fulfilled, building can be achieved via one of the presets or by calling cmake directly.

** Presets

Pixelarium has a few presets setting specific compilers and configurations defined in =CMakePresets.json=.

They can be listed by calling
#+begin_src sh :results raw :wrap src sh
  cmake --list-presets
#+end_src
which will give something like
#+RESULTS:
#+begin_src sh
Available configure presets:

  "clang-release"
  "clang-debug"
  "gcc-release"
  "gcc-debug"
#+end_src

Building with the =clang-debug= preset would look like
#+begin_src sh
  cmake --preset clang-debug
  cmake --build --preset clang-debug
#+end_src

** Direct

If you want to specify compiler settings and options which are not defined in a preset, use cmake "directly" like
#+begin_src sh
  cmake -B build -S .
  cmake --build build
#+end_src
