Build: add scripts to build dependencies for Windows and macOS.

Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.

Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.

+# basename_LIBRARY_RELEASE depending on what has been found and set.  If only
+# basename_LIBRARY_RELEASE is defined, basename_LIBRARY, basename_LIBRARY_DEBUG,

+#
+# If the generator supports configuration types, then basename_LIBRARY and
+# basename_LIBRARIES will be set with debug and optimized flags specifying the
+# library to be used for the given configuration.  If no build type has been set
+# or the generator in use does not support configuration types, then
+# basename_LIBRARY and basename_LIBRARIES will take only the release values.
