No CMAKE_C_COMPILER could be found.

This error message typically occurs when CMake cannot find a C compiler on your system. To resolve this issue, you can try one of the following solutions:

1. Install a C compiler on your system. For example, if you are using Ubuntu or Debian, you can install the GNU C compiler by running the following command in your terminal:

   sudo apt-get install gcc

2. Set the C compiler path in your CMakeLists.txt file. You can do this by adding the following line to your CMakeLists.txt file:

   set(CMAKE_C_COMPILER /path/to/your/c/compiler)

Replace "/path/to/your/c/compiler" with the path to your C compiler.

3. If you are using an IDE, make sure that it is configured to use the correct C compiler. Check the IDE's settings or preferences to ensure that the correct compiler is selected.

Once you have resolved the issue, try running CMake again.
