+proteins, lipids and nucleic acids that have a lot of complicated bonded
+interactions, but since GROMACS is extremely fast at calculating the nonbonded
+interactions (that usually dominate simulations) many groups are also using it
+for research on non-biological systems, e.g. polymers.  GROMACS supports all the
+usual algorithms you expect from a modern molecular dynamics implementation.")

+Unbundling tinyxml2 from gromacs and using our own, which is newer, broke gromacs
+build.
+
+This patch fixes three issues:
+
+- cmake now errors out if using multiple target_link_libraries with mixed styles
+  of signatures.
+
+- Error handling API changed, fix the testutils/refdata_xml.cpp code by using the
+  new API: document.ErrorStr() & tinyxml2::XML_SUCCESS.
+
+Those fixes will be submitted for inclusion to upstream, but may not be suitable
+there as long as they still keep the old version bundled.
+
+First hunk has already been requested for merging. Third is in discussion. Second
+will only be sent if third is OK'ed.
