+
+    Don't use wingenminiupnpcstrings when generating miniupnpcstrings.h
+
+    The wingenminiupnpcstrings tool is used on Windows to generate version
+    information. This information is irrelevant for us, and trying to use
+    wingenminiupnpcstrings would cause builds to fail, so just don't use it.
+
+    We should be able to drop this once we are using 2.1 or later. See
+    upstream commit: 9663c55c61408fdcc39a82987d2243f816b22932.

+    Disable threading to fix non-determinism
+
+    A bug in the file parser can cause dependencies to be calculated
+    differently based on which files have already been parsed. This is more
+    likely to occur on systems with more CPUs.
+
+    Just disable threading for now. There is no noticable slowdown.
+
+    See #9891.

+    Don't hardcode pwd path
+
+    Let a man use his builtins if he wants to! Also, removes the unnecessary

+
+    Fix backwards compatibility with older Freetype versions at runtime
+
+    A few years ago, libfreetype introduced FT_Get_Font_Format() as an alias
+    for FT_Get_X11_Font_Format(), but FT_Get_X11_Font_Format() was kept for abi
+    backwards-compatibility.
+
+    Qt 5.9 introduced a call to FT_Get_Font_Format(). Replace it with FT_Get_X11_Font_Format()
+    in order to remain compatibile with older freetype, which is still used by e.g. Ubuntu Trusty.
+
+    See #14348.
