Remove awk dependency when building using CMake. Before this awk was required

for -DWITH_MODULES option.

* build/build-modules-c.cmake:
  (generate_builtin_modules_c): Function to generate modules.c.

* CMakeLists.txt
  (): Use generate_builtin_modules_c() instead of `awk -f build/build-modules-c.awk`
  to generate modules.c file.

* README.cmake: 
  (Prerequisites, How to build): Do not mention awk as prerequisite.

2. Make sure cmake and Perl are in PATH. Additionally, some backends
require compile tools in PATH. (Hint: "Visual Studio Command Prompt")
