title: How to install Cmake C compiler and CXX compiler
body: <p>I need some help compiling this project with cmake. Here is the error message.</p>
  
  <pre><code>$ ./build_avida
  -- Building for: NMake Makefiles
  CMake Warning at CMakeLists.txt:1 (PROJECT):
    To use the NMake generator, cmake must be run from a shell that can use the
    compiler cl from the command line.  This environment does not contain
    INCLUDE, LIB, or LIBPATH, and these must be set for the cl compiler to
    work.
