[CMake] Splitting directory and file.

[Pablo Zurita]

Thanks for the help guys. With that I was able to write the following
function that allows me to deal with my source as I want.

	# create_source_group(relativeSourcePath sourceGroupName files)
	#
	# Creates a source group with the specified name relative to the relative path
	# specified.
	#
	# Parameters:
	#	- sourceGroupName: Name of the source group to create.
	#	- relativeSourcePath: Relative path to the files.
	#	- sourceFiles: Files to add to the source group.
	#
	# For example if you have the following directory structure:
	#
	#	- ExampleApplication
	#		- include
	#			- Main.h
	#				- Window
	#					Window.h
	#		- source
	#			- Main.cpp
	#				- Window
	#					Window.cpp
	#
	# You can get your list of files and call create_source_group the following way
	#
	#	file(GLOB_RECURSE my_source_files ${CMAKE_CURRENT_SOURCE_DIR}/source/*)
	#	create_source_group("Source Files"
"${CMAKE_CURRENT_SOURCE_DIR}/source" ${my_source_files})
	#	file(GLOB_RECURSE my_header_files ${CMAKE_CURRENT_SOURCE_DIR}/include/*)
	#	create_source_group("Header Files"
"${CMAKE_CURRENT_SOURCE_DIR}/include" ${my_header_files})
	#	add_executable(ExampleApplication ${my_source_files} ${my_header_files})
	#
	# Then the generated solution would look like this
	#
	#	- ExampleApplication (project)
	#		- Header Files
	#			- Main.h
	#				- Window
	#					Window.h
	#		- Source Files
	#			- Main.cpp
	#				- Window
	#					Window.cpp
	#
	function(create_source_group sourceGroupName relativeSourcePath sourceFiles)
		FOREACH(currentSourceFile ${ARGN})
			FILE(RELATIVE_PATH folder ${relativeSourcePath} ${currentSourceFile})
			get_filename_component(filename ${folder} NAME)
			string(REPLACE ${filename} "" folder ${folder})
			if(NOT folder STREQUAL "")
				string(REGEX REPLACE "/+$" "" folderlast ${folder})
				string(REPLACE "/" "\\" folderlast ${folderlast})
				SOURCE_GROUP("${sourceGroupName}\\${folderlast}" FILES ${currentSourceFile})
			endif(NOT folder STREQUAL "")
		ENDFOREACH(currentSourceFile ${ARGN})
	endfunction(create_source_group)


Thanks,
Pablo Zurita.
