Ah then maybe I don't understand correctly what is supposed to be displayed by ccmake.
In general, how can I have in the ccmake screen some variables displayed to configure some paths to some libraries?

For example I would like the user to be able to edit BOOST_ROOT when calling ccmake, how can I do that? Right now all I see when first running ccmake is "EMPTY_CACHE", and when typing "c" to configure (which fails because some variables aren't properly set) then "e" to exit, I see the variables I have defined with "option", and I can toggle those, but I don't see other variables. I have tried the following: if(NOT DEFINED BOOST_ROOT) set(BOOST_ROOT "/usr" CACHE PATH "Root of the Boost installation") endif(NOT DEFINED BOOST_ROOT) But I still don't see it in the list of variables. CACHE variables are "Advanced Variables" which are not displayed unless you toggle display advanced var in either ccmake or cmake-gui. In ccmake you have to hit 't' in order to see advanced variables. Additionally, is there a way to have set of variables (namely the options, as well as things like BOOST_ROOT, CMAKE_CXX_COMPILER, CMAKE_C_COMPILER) show up when first calling ccmake, instead of EMPTY_CACHE? I don't know, CMAKE_<lang>_COMPILER is not meant to be set with cmake UI, they ought to be set in a toolchain or outside. As noted in CMakeForceCompiler module you should not force them, use toolchain or env var before calling cmake* tool. -- Eric
