# Finally, compile/install PDF2SVG as a static binary
# For static compilation to work, all dependencies have to be
# mentioned individually one by one for the linker. We use pkg-config
# to generate appropriate compiler and linker flags for most libraries.
# For some of them, this doesnt work and/or they must come
# at a specific argument position, so we list them separately.
