 #  Description:
 #    Several functions that help organising the source tree.
 #    [ADD/SET]_SOURCE_FILES - Writes source files to the cache by force and
 #                             adds the current directory.
 #    GET_ALL_HEADER_FILES - Finds all header files recursively.
 #    GENERATE_SOURCE_GROUPS - Set Visual Studio source groups.
 #

# Adds source files with the full path to a list
FUNCTION(ADD_SOURCE_FILES _varname)
  # Prefix the full path
  SET(_fullpath_sources)
  FOREACH(_file ${ARGN})
    GET_SOURCE_FILE_PROPERTY(_filepath ${_file} LOCATION)
    LIST(APPEND _fullpath_sources ${_filepath})
  ENDFOREACH(_file)
  # Write into the cache to avoid variable scoping in subdirs
  SET(${_varname} ${${_varname}} ${_fullpath_sources} CACHE INTERNAL "Do not edit")
ENDFUNCTION(ADD_SOURCE_FILES)


# Sets source files with the full path
FUNCTION(SET_SOURCE_FILES _varname)
  # Prefix the full path
  SET(_fullpath_sources)
  FOREACH(_file ${ARGN})
    GET_SOURCE_FILE_PROPERTY(_filepath ${_file} LOCATION)
    LIST(APPEND _fullpath_sources ${_filepath})
  ENDFOREACH(_file)
  # Write into the cache to avoid variable scoping in subdirs
  SET(${_varname} ${_fullpath_sources} CACHE INTERNAL "Do not edit")
ENDFUNCTION(SET_SOURCE_FILES)


# Search the entire directory tree for header files and add them to a variable
MACRO(GET_ALL_HEADER_FILES _target_varname)
  FILE(GLOB_RECURSE ${_target_varname} ${CMAKE_CURRENT_SOURCE_DIR} "*.h")
