Hi,
I am currently still learning how to use dealii libraries.
Just recently I was trying to use step-4 examples.
Just recently I was trying to use step-4 examples.
so i did the usual by inputing: " cmake . " within the directory.
What happened was I received this:
What happened was I received this:
"CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.16)
should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.

and then when I key in " make " nothing seems to happen.
Would someone kindly guide me to what I am supposed to do here?
I am not very familiar with cmake myself so I'm learning by doing everything at the moment.
Kind regards,

Did you accidentally run "cmake ." in "examples/" instead of
"examples/step-4"?
