# When calling pkg-config --static --libs, pkg-config will always output the
# regular libs first, and then the extra libs from Libs.private field,
# since the assumption is that those are additional dependencies for building
# statically that the .a files depend upon. The output order of .pc fields is:
#   Libs   Libs.private   Requires   Requires.private
# The fields Requires* are for package names.
# The flags of the DPDK libraries must be defined in Libs* fields.
# However, the DPDK drivers are linked only in static builds (Libs.private),
# and those need to come *before* the regular libraries (Libs field).
# This requirement is satisfied by moving the regular libs in a separate file
# included in the field Requires (after Libs.private).
