Migrate gpgpu-sim build system to cmake (#66)

* migrate_cmake: add package dependency checking

* migrate_cmake: port setup_environment to CMake

* migrate_cmake: break dependency checking and env export gen to different .cmake files

* migrate_cmake: use CUDAToolkit_FOUND to test for CUDA compiler

* migrate_cmake: use CUDAToolkit_FOUND to test for CUDA compiler

* migrate_cmake: use CUDAToolkit_FOUND to test for CUDA compiler

* migrate_cmake: properly parse for cuda version number

* migrate_cmake: set highest CUDA supported to be 11.10.x

* migrate_cmake: specify top level CMake file

* migrate_cmake: add libcuda cmake file

* migrate_cmake: use global compiler options and definitions

* migrate_cmake: add cmake file to src

* migrate_cmake: add cmake files for cuda-sim folder

* migrate_cmake: add cmake files to gpgpu-sim folder

* migrate_cmake: add cmake files for intersim

* migrate_cmake: add short test using cmake

* migrate_cmake: bump CXX standard requirement to 17

* Add cmake files for accelwattch

* migrate_cmake: remove use of GLOB to grab source files

* migrate_cmake: comment out the write protection on generated instructions.h

* migrate_cmake: create sym folder and add newline to generated setup file

* migrate_cmake: fix some path issues

* migrate_cmake: let cmake thinks flex and bison generate CXX files

* migrate_cmake: fix not linking pthread properly

* migrate_cmake: remove debug message

* migrate_cmake: add empty libopencl cmake file

* migrate_cmake: install phase and runtime version detect

	* Added install phase to install the shared object
	  and add symlinks

	* Changes with CUDA toolkit will be detected and
	  triggered a rebuild

	* GPGPU-Sim detailed version string will be updated
	  on each build

* Typo fix and fix correct bin dir

* Replace gcc -> g++ in intersim

* ignore setup

* check CMAKE_BUILD_TYPE

* set DCMAKE_BUILD_TYPE
