I am trying to figure out CMake and can't seem to figure out this basic issue. Every time I try to configure the project using CMake GUI it gives me an error stating the "source directory does not appear to contain CMakeLists.txt" when it clearly does. The text of the CMakeLists.txt file is:

```
cmake_minimum_required(VERSION "3.19.0")

project("Hello_World")

add_executable("${PROJECT_NAME}" "main.cpp")

install (TARGETS "${PROJECT_NAME}" DESTINATION bin)

install (FILES "main.cpp" DESTINATION src)

```

Also here is an image of my screen with all the relevant info:

When I navigate to the Hello\_World directory in the console and enter cmake, I get this:

```
Usage

  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>
  cmake [options] -S <path-to-source> -B <path-to-build>

Specify a source directory to (re-)generate a build system for it in the
current working directory.  Specify an existing build directory to
re-generate its build system.

Run 'cmake --help' for more information.

```

What am I missing? Any help would be appreciated. Thanks.
