CMake Error : does not appear to contain CMakeLists.txt

Hi everyone
I encounter such an error when installing Geant4!

CMake Error: The source directory “/usr/local/include/geant4-build” does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Geant4 Version: 10.7.4
_Operating System:_Ubuntu 20.04
Compiler/Version: GCC 11.4.0
_CMake Version:_3.26.5

thanks in advance for your helps

You shouldn’t be specifying your build directory as your source directory. You should specify the actual source directory (i.e., where did you unpack the Geant4 tarball?).
