You can try to pass CFLAGS, CXXFLAGS and LDFLAGS to CMake by overriding dh_auto_configure with e.g. CFLAGS:=$(shell dpkg-buildflags --get CFLAGS) CXXFLAGS:=$(shell dpkg-buildflags --get CXXFLAGS) #CFLAGS+=$(CXXFLAGS) dh_auto_configure -- \ -DCMAKE_C_FLAGS="$(CFLAGS)" \ -DCMAKE_CXX_FLAGS="$(CXXLAGS)" You can also pass CXXFLAGS to CFLAGS or vice versa. It depends mostly on upstream's (broken) build system. Sometimes they forget to add variables for custom CFLAGS or CXXFLAGS to CMakelist.txt. Your other option is then to patch CMakelist.txt and forward the changes upstream. [...] > My original plan was to replace all graphics by colored rectangles with text > inside.

The idea is to provide users of the engine with enough material and information, so that they are able to create more content and improve the current status. It's a common problem that people develop some sort of free engine but don't provide free game data as well. However I believe we are not only here to package games but also to provide tools for game development. Free data packages are a contribution to these efforts. > Though when I approached > upstream about this solution for getting vcmi into Debian main instead of > contrib I met only criticism.

It's a simple packaging issue. VCMI is the free engine and Heroes of Might and Magic 3 is the (non-free) game. The game should depend on the engine not vice versa. That leaves you with the following options: If Heroes of Might and Magic is non-free but distributable, you can prepare a package for non-free which in turn depends on vcmi. If the game is non-free and non-distributable game-data-packager is your tool of choice. You can avoid any criticism when you create a distinct vcmi-data package that provides enough data for demonstrating the basic gameplay and perhaps some documentation how people can built upon this work. Then vcmi-data (main) depends on vcmi (main) and Heroes3 (non-free) also depends on vcmi (main). If the package description is meaningful enough, those who want to play Heroes3 have to install the non-free data package and everyone else can start developing a free replacement. It would be great if upstream developed some free tools so that others could create more free content for their engine. Regards, Markus
