= CMake Macro Reference: `boost_additional_test_dependencies` =

The `boost_additional_test_dependencies` macro adds additional include directories based on the dependencies of the library being tested 'libname' and all of its dependencies.

{{{
boost_additional_test_dependencies(libname 
                        BOOST_DEPENDS libdepend1 libdepend2 ...)
}}}

`libname` is the name of the boost library being tested. (signals)

There is mandatory argument to the macro: 

`BOOST_DEPENDS`: The list of the extra boost libraries that the test suite will
depend on. You do NOT have to list those libraries already listed by the 
module.cmake file as these will be used.

== Example ==

The following invocation of the `boost_additional_test_dependencies` macro is taken from the signals library.
{{{
  boost_additional_test_dependencies(signals BOOST_DEPENDS test optional)
}}}

== Where Defined ==
This macro is defined in the Boost Testing module in [http://svn.boost.org/svn/boost/trunk/tools/build/CMake/BoostTesting.cmake
