# MITK_MULTIPLEX_PICTYPE: generate separated source files for different
# data types to reduce memory consumption of compiler during template
# instantiation
#
# Param "file" should be named like mitkMyAlgo-TYPE.cpp
# in the file, every occurence of @TYPE@ is replaced by the
# datatype. For each datatype, a new file mitkMyAlgo-datatype.cpp
# is generated and added to CPP_FILES_GENERATED.
