Are you using a static vpx library on purpose?  The vpx.pc file needs
a -lpthread in its Libs.private line (that's a libvpx bug) but you
probably want to use a shared library libvpx instead (which wont have
this problem).  If you compiled libvpx from source, configure it again
and pass --disable-static, recompile and install (and remove the
libvpx.a library from ~/install/lib).

Those flags are only used when linking poppler programs (clients/view).
