+From: Lars Wendler <polynomial-c@gentoo.org>
+Date: Fri, 1 Mar 2019 23:11:41 +0100
+Subject: [PATCH] Set some proper paths to make cmake find our tools.
+
+The ebuild now adds an extra / at the end of $EPREFIX so that it is
+never the empty string (so that CMAKE_SYSTEM_PREFIX_PATH remains
+correct)
+
+Original patch by Heiko Przybyl.

+Subject: [PATCH 4/6] Ensure that the correct version of Qt is always used.
+
+With the introduction qt-4.8.6, Qt binaries were moved from /usr/bin to
+/usr/$(get_libdir)/qt4/bin, leaving behind in their place symlinks to qtchooser.
+
+There is no guarantee to which version of Qt these symlinks might point, so it
+is necessary to find the correct version explicitly.
+
+Once qmake is found, it is queried for the correct location of all other items.

+Subject: [PATCH] FindPkgConfig: ignore whitespace separators in version check
+
+The regex used to split up the version if it contains an operator fails
+if the string contains whitespaces. Resulting in an extra whitespace
+after the package name and before the package version leading to
+breakage in pkgconf and thus webkit-gtk.

+Subject: [PATCH] Tests: Improve C compatibility of LoadCommand tests
+
+The previous code used `char **` and `const char **`` types as if they
+were the same.  But they are distinct types in C, so when passing
+these pointers as function arguments, their types have to match.
+Future C compilers will treat this as an error, similar to what
+C++ compilers do today.

+Ensure that the correct version of Qt is always used.
+
+With the introduction qt-4.8.6, Qt binaries were moved from /usr/bin to
+/usr/$(get_libdir)/qt4/bin, leaving behind in their place symlinks to qtchooser.
+
+There is no guarantee to which version of Qt these symlinks might point, so it
+is necessary to find the correct version explicitly.
+
+Once qmake is found, it is queried for the correct location of all other items.
