In defense of the original post, --enable-foo is much more readable than -DENABLE_FOO or -DUSE_FOO. Having implemented USE_FOO arguments for every single one of our optional dependencies and looked at them on a CMake command line I can attest to this. :) I love CMake, but there have been times when I wished that --enable-foo would simply be a shortcut to set a boolean variable ENABLE_FOO to true. >> windows also has its ugly CmakeSetup gui. > > un*x version of cmake has menu driven UI too > did you try ccmake (note the double 'c') > > <joke> > personnally I think the ugliness of GUI app most > of time comes from the GUI concept itself :=)) > command line is far more powerful. > </joke> <joke> Real men edit CMakeCache.txt manually. :) </joke> > >> However, neither approach seems to me as clean as what's available under >> autotools. > > I personnally think the OPTION CMake macro is just as good > as AC_ARG_ENABLE is. Almost. Automake has a neat feature the original poster pointed out that uses arguments to AC_ARG_ENABLE to output documentation when you call "./configure --help". CMake doesn't have an equivalent feature I know of for this but I think the closest would be a visual inspection of the variables in "ccmake" or "CMakeSetup.exe". -- Philip Lowman Simulation Development Engineer, Modeling and Simulation Technology General Dynamics Land Systems http://www.gdls.com _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
