+Add ZLIB_INCLUDE_DIR variable
+
+On Linux platform[1], the build system forces to use zlib from the
+system instead of compiling the one located intree.
+
+The following error is raised when the zlib header is installed
+somewhere else than in the default system include path:
+
+	ssl3con.c:39:18: fatal error: zlib.h: No such file or directory
+	 #include "zlib.h"
+
+The same trick setup for sqlite include directory is reproduced for
+zlib. The build system disallows in any manner to give arguments to the
+compiler explicity.
+
+The variable ZLIB_INCLUDE_DIR point to the directory where the zlib
+header is located.
