-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.
