Update third-party dependencies
Updated the third-party dependencies:
- boost 1.72.0
- cairo 1.16.0
- curl 7.67.0 (new: poppler was built with curl support)
- Expat 2.2.9
- FreeType 2.10.1
- lcms 2.9
- libiconv 1.16
- libpng 1.6.37
- libjpeg-turbo 2.0.3
- LibTIFF 4.1.8
- OpenJPEG 2.3.1
- pixman 0.38.4
- poppler 0.84.0
- poppler-data 0.4.9
- Qt 5.14.0
- Xz Utils liblzma 5.2.4
- zlib 1.2.11
Note that I reintroduced libjpeg-turbo
; as this time, I compiled every library (including Qt) using MSVC 2019, I disabled Qt's own libraries where possible. Hopefully, this fixes the image problems (dannyedel#99) - my previous solution was to use the deprecated internal DCT decoder of poppler.
