+ <para>
+ Provides a means of enabling or disabling features of a
recipe
+ on a per-recipe basis. The
<filename>PACKAGECONFIG</filename>
+ variable itself specifies a space-separated list of the
features
+ to enable, whilst the named flags set on the variable
specify
+ for each feature the additional build dependencies
+ (<filename><link
linkend='var-DEPENDS'>DEPENDS</link></filename>)
+ that should be added if the feature is enabled, and any
extra arguments
+ that should be added to the configure script argument list
+ (<filename><link
linkend='var-EXTRA_OECONF'>EXTRA_OECONF</link></filename>)
+ if the feature is enabled or disabled.
+ </para>
+ <para>
+ For example, the following taken from the
<filename>librsvg</filename>
+ recipe will add <filename>--with-croco</filename> to the
+ configure script arguments and
<filename>libcroco</filename> to
+ <filename><link
linkend='var-DEPENDS'>DEPENDS</link></filename>
+ by default; however, if "croco" is removed from
<filename>PACKAGECONFIG</filename>
+ (for example, by using a bbappend in another layer) then
+ <filename>--without-croco</filename> will be added to the
configure
+ script arguments instead:
+ <literallayout class='monospaced'>
+ PACKAGECONFIG ??= "croco"
+ PACKAGECONFIG[croco] = "--with-croco,--without-croco,libcroco"
+ </literallayout>
