There are two options I see... 1. Force the build to use UNIX makefiles (just for that part of the build). Is this an option for Android? 2. I haven't done more that do a couple of google searches but it looks like it's possible to call "cmake --build --target" instead and then let cmake figure it out. So line 81 would change to something like: BUILD_COMMAND ${CMAKE_COMMAND} --built --target generate_codebook Not exactly sure when I'll have time to test it but if that gives you enough to go on please try it out. Thanks, Richard
