# Macros
# =========
#
# In some cases it can be necessary or useful to invoke the Qt build tools in a
# more-manual way. Several macros are available to add targets for such uses.
#
# ::
#
#   macro qt5_generate_repc(outfiles infile outputtype)
#         out: outfiles
#         in: infile outputtype
#         create C++ code from a list of .rep files. Per-directory preprocessor
#         definitions are also added.
#         infile should be a replicant template file (.rep)
#         outputtype specifies output file type, it can be one of SOURCE|REPLICA
#         Example usage: qt5_generate_repc(LIB_SRCS interface.rep SOURCE)
#           for generating interface_source.h and adding it to LIB_SRCS
