Fiber: Self-contained LaTeX Editor with Tectonic

Under development. I had to add these flags to have cargo recongize external dependencies; my Mac fails to build with vendored versions of the tectonic crate's dependencies. Add these to .zshrc (or run once via environment variables). Install the packages in the first export line with brew.

export PKG_CONFIG_PATH="$(brew --prefix harfbuzz)/lib/pkgconfig:$(brew --prefix icu4c)/lib/pkgconfig:$(brew --prefix graphite2)/lib/pkgconfig:$(brew --prefix freetype)/lib/pkgconfig:$(brew --prefix libpng)/lib/pkgconfig:${PKG_CONFIG_PATH}"
export CPPFLAGS="-I$(brew --prefix harfbuzz)/include ${CPPFLAGS}"
export C_INCLUDE_PATH="$(brew --prefix harfbuzz)/include:${C_INCLUDE_PATH}"
export CPATH="$(brew --prefix harfbuzz)/include:${CPATH}"
export CFLAGS_aarch64_apple_darwin="-I$(brew --prefix harfbuzz)/include ${CFLAGS_aarch64_apple_darwin}"
export CXXFLAGS="-std=c++17 ${CXXFLAGS}"
