SET(FLTK11_USE_FILE "/usr/share/cmake/Modules/FLTKUse.cmake") which doesn't get installed by this version, it seems.
And the FLTK_VERSION_* values seem wrong, too. Do you have many cmake projects that actually use this file (instead of fltk-config)?
(In reply to comment #2) > And the FLTK_VERSION_* values seem wrong, too. Do you have many cmake > projects that actually use this file (instead of fltk-config)? I just stumbled upon this handling oyranos version bump/buildsystem switch (bug 450494).
It looks like the autotools build system does not use CMake/*cmake.in to generate the files we install. Only the cmake build system does that.
