CMake build system for pdfium

This repo provides cmake build scripts for pdfium. The upstream project uses gn, one of many symptoms of Google's NIH syndrome.

The aim of this repo is to ease building pdfium for multiple platforms. Third party dependencies are provided by system packages, instead of vendored libraries.

Usage

1. Download pdfium sources using the download_pdfium.py python script.
2. Run cmake with the PDFIUM_ROOT configuration variable set to the location of the downloaded sources. It has some options to enable/disable features (not all features are currently supported). All pdfium related options have a PDF_ prefix.

sources.yml

This file contains the git hashes + urls where the pdfium sources + essential dependencies can be downloaded. It provides 2 versions of pdfium sources: current and master.

• current is a collection of fixed git hashes of pdfium sources which are guaranteed to build with these cmake scripts.
• master contains the dynamic develop git branches of pdfium. Because these are dynamic in nature, they might fail.

Test coverage

Tested platforms

The cmake scripts are tested by CI on:

• Linux:
  • ubuntu packages
  • conan packages
• Macos:
  • conan packages
• Windows:
  • conan packages

Patches for testing + running on other platforms are welcome.

Tested options

• Pdfium is built in static and shared configuration

Only the default options are currently tested. Code for building pdfium sources making use of skia/v8 is implemented but not working. Patches are welcome.
