[SOLVED] Problem in installing Cmake

Hi @Hugo
I installed it in Linux ubuntu 16.04, I had Ros before, so it had Cmake 3.5.2, So I uninstalled the older Cmake first by (sudo apt-get remove Cmake and sudo apt-get autoremove –purge cmake). then start to install the Cmake 3.16.6.
Cmake it seems working well when I run CMake-GUI in the build directory of SOFA.
Cmakes open and after clicking the configuration button. this error appeared then generation didn’t complete, So I can not use make or ninja in the next step. I tried Ninja and Unix Makefile and none of them worked.
I uninstalled the Cmake and installed another version(3.13.4) and try it again, but I received the same error. then I tried to deselect some items in Cmake entries to find the problem, I don’t know I have the right to do it or not, Maybe I shouldn’t do that. is it possible to roll back to before changes?
every time Cmake keeps the caches even after uninstalling it completely. is there any way to remove it completely? Should I reinstall Linux?
Many Thanks
Amir
