Frank,
IMHO, something that is missing in the actual build system is a way to allow
the user to specify additional libraries to link with without modifying
nmake.opt.
It is possible to specify some include folders with EXTRAFLAGS but no way to
initialize for example the ADD_LIBS variable.
This should be possible with a very minor change to nmake.opt :
Just replace the line :
# Any extra libraries needed on this platform?
ADD_LIBS =
With something like :
# Any extra libraries needed on this platform?
ADD_LIBS = $(ADD_LIBS)
With that, it is possible to specify additional libraries in nmake.opt or in
the EXT_NMAKE_OPT file.
For example :
#
# JPEG LS (lossless jpeg)
#
EXTRAFLAGS = $(EXTRAFLAGS) -DFRMT_jpegls
HAVE_CHARLS = yes
CHARLS_INC = -I$(3RDPARTY)/CharLS-1.0
CHARLS_LIB = $(3RDPARTY)/CharLS-1.0/$(BUILD_MODE)/CharLS.lib
ADD_LIBS = $(ADD_LIBS) $(CHARLS_LIB)
Best regards,
Frédéric.
