>Description</H2
><P
>Most packages export one or more header files defining their public
interface. For example the C library exports header files such as
<TT
CLASS="FILENAME"
>stdio.h</TT
> and
<TT
CLASS="FILENAME"
>ctype.h</TT
>.
If the package follows the <A
HREF="package.html#PACKAGE.HIERARCHY"
>directory
layout conventions</A
> then the exported header files will normally
be found in the package's
<TT
CLASS="FILENAME"
>include</TT
> sub-directory. For
packages which do not follow these conventions, typically simple ones
for which a complicated sub-directory hierarchy is undesirable, there
has to be an alternative way of specifying which header file or files
define the public interface. The <SPAN
CLASS="PROPERTY"
>include_files</SPAN
> property provides
support for this.</P
><P
>By default, if a package does not have an
<TT
CLASS="FILENAME"
>include</TT
> subdirectory and it
does not have an <SPAN
CLASS="PROPERTY"
>include_files</SPAN
> property then all files with a suffix
of <TT
CLASS="LITERAL"
>.h</TT
>, <TT
CLASS="LITERAL"
>.hxx</TT
>,
<TT
CLASS="LITERAL"
>.inl</TT
> or <TT
CLASS="LITERAL"
>.inc</TT
> will be treated as
public header files. However some of these may be private files
containing implementation details. If there is an
<SPAN
CLASS="PROPERTY"
>include_files</SPAN
> property then only the files listed in that property
will be exported.</P
><P
>If a package should not export any header files but does contain
private implementation headers, an <SPAN
CLASS="PROPERTY"
>include_files</SPAN
> property with no
arguments should be used.</P
