How to locate C, C++, and Fortran compilers on my win7x64 machine?

Question

I'm trying to build binary files of the LAPACK 3.7.0 using CMAKE based on what is told here. In order to use them in my Visual Studio 2013 C++ project.
But I really don't know which option should I choose here?

And also which compilers should I choose in the following?

Because I can't find them in the suggested directories within Program Files or Program File(x86) folders. my machine uses a dual-core Intel(R) Core(TM) 2 Duo CPU

When using Visual Studio < 2015, a common solution is to run CMake GUI from Visual Studio Command line.

Use windows start menu to run "Visual Studio Command Prompt"

Run cmake-gui from command line. If the folder is in your path, simply launch cmake-gui. If not, launch it using the full path

Locate the source folder of your project (the folder containing the top-level CMakeLists.txt) and create a new build folder (ex c:/my-project/build_32). Generating an environment in the source folder is discouraged) Generate your project selecting the right MSVC version. In your case, it will be "Visual Studio 12 2013". In my case, this is MSVC 2010.

That's all. Click on finish button and it should generate the compilation environment, solutions, projetcs, etc.

This will generate environment for compiling x86 application. If you also need to compile a x64 version of your project, simply follow again that process, generating in a new build folder and selection "Visual Studio 12 2013 Win64".

By default, if you have a paid version of Visual Studio you have both x86 and Win64 compiler installed. If you have the express version, you only have the x86 compiler (so generation using MSVC Win64 will fail).
