[CMake] Extending CMake

[dfeustel at mindspring.com]

I am trying to create the loadable command described
on page 147 of _Mastering CMake_ ver 2.2.

I have typed in the file cmHELLO_WORLD.c


#include "cmCPluginAPI.h"

	static int InitialPass(void *inf, void *mf, int argc, char *argv[])
	{
		cmLoadedCommandinfo *info = (cmLoadedCommandInfo *)inf;
		info->CAPI->AddDefinition(mf, "FOO", "DAR");

		return 1;
	}

	void CM_PLUGIN_EXPORT
	HELLO_WORLDInit (cmLoadedCommandInfo *info)
	{
		info->InitialPass = InitialPass;
		info->Name = "HELLO_WORLD";
	}


the file CMakeLists.txt 


	PROJECT (HELLO_WORLD)

	SET (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}"
		"${CMAKE_ANSI_CXXFLAGS}"
		)

	SET (CMAKE_C_FLAGS "${CMAKE_C_FLAGS}"
		"${CMAKE_ANSI_CFLAGS}"
		)

	INCLUDE_DIRECTORIES(${CMAKE_ROOT}/include
		${CMAKE_ROOT}/Source
		)

	ADD_LIBRARY (cmHELLO_WORLD MODULE cmHELLO_WORLD.c)

When I run ccmake -, it seems to work.


But when I then run make, I get the error message

[100%] Building C object CMakeFiles/cmHELLO_WORLD.dir/cmHELLO_WORLD.o
*** Error code 1

Stop in /home/daf/Cm/Plugin (line 53 of CMakeFiles/cmHELLO_WORLD.dir/build.make).
*** Error code 1

Stop in /home/daf/Cm/Plugin (line 53 of CMakeFiles/Makefile2).
*** Error code 1

Stop in /home/daf/Cm/Plugin (line 66 of Makefile).

Are the source code files for this example available online for download?

Thanks,
