# Project Modules
#

#| Note: This is the only section you probably want to modify
#| Each module is defined by it's own folder (e.g. Scan/Matrix represents the "Matrix" module)
#| All of the modules must be specified, as they generate the sources list of files to compile
#| Any modifications to this file will cause a complete rebuild of the project

#| Please the {Scan,Macro,USB,Debug}/module.txt for information on the modules and how to create new ones

##| Deals with acquiring the keypress information and turning it into a key index
set(  ScanModule  "MBC-55X" )

##| Uses the key index and potentially applies special conditions to it, mapping it to a usb key code
set( MacroModule  "buffer"  )

##| Sends the current list of usb key codes through USB HID
set(   USBModule  "pjrc"   )

##| Debugging source to use, each module has it's own set of defines that it sets
set( DebugModule  "full"   )

# Module Overrides (Used in the buildall.bash script)

if ( ( DEFINED ${ScanModuleOverride} ) AND ( EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/Scan/${ScanModuleOverride} ) )
	set( ScanModule ${ScanModuleOverride} )
endif ( ( DEFINED ${ScanModuleOverride} ) AND ( EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/Scan/${ScanModuleOverride} ) )



###
# Path Setup
# 
set(  ScanModulePath  "Scan/${ScanModule}"  )
set( MacroModulePath "Macro/${MacroModule}" )
set(   USBModulePath   "USB/${USBModule}"   )
set( DebugModulePath "Debug/${DebugModule}" )

#| Top-level directory adjustment
set( HEAD_DIR "${CMAKE_CURRENT_SOURCE_DIR}" )



###
# Module Check Function
#

#| Usage:
#|  PathPrepend( ModulePath <ListOfFamiliesSupported> )
#| Uses the ${COMPILER_FAMILY} variable
function( ModuleCompatibility ModulePath )
	foreach( mod_var ${ARGN} )
		if ( ${mod_var} STREQUAL ${COMPILER_FAMILY} )
			# Module found, no need to scan further
			return()
		endif ( ${mod_var} STREQUAL ${COMPILER_FAMILY} )
	endforeach( mod_var ${ARGN} )

	message( FATAL_ERROR "${ModulePath} does not support the ${COMPILER_FAMILY} family..." )
endfunction( ModuleCompatibility ModulePath )



###
# Module Configuration
#

#| Additional options, usually define settings
add_definitions()

#| Include path for each of the modules
add_definitions(
	-I${HEAD_DIR}/${ScanModulePath}
	-I${HEAD_DIR}/${MacroModulePath}
	-I${HEAD_DIR}/${USBModulePath}
	-I${HEAD_DIR}/${DebugModulePath}
)




###
# Module Processing
#

#| Go through lists of sources and append paths
#| Usage:
#|  PathPrepend( OutputListOfSources <Prepend Path> <InputListOfSources> )
macro( PathPrepend Output SourcesPath )
	unset( tmpSource )

	# Loop through items
	foreach( item ${ARGN} )
		# Set the path
		set( tmpSource ${tmpSource} "${SourcesPath}/${item}" )
	endforeach( item )

	# Finalize by writing the new list back over the old one
	set( ${Output} ${tmpSource} )
endmacro( PathPrepend )
