hristo 6e79476650 Fixed the build for web using CMake. (#1452) 
* Fixed the build for web using CMake.

I found that the build for me was failing and I added some if defined checks in the core.c file where the glfwSetWindowAttrib was used. (error: implicit declaration of function 'glfwSetWindowAttrib' is invalid in C99 [-Werror,-Wimplicit-function-declaration])

I also changed some values in the toolchain file so that it correctly uses the .bat files when on windows.

* Cleaned up the additional variables (they are not important)

* Added more improvements to cmakelists

Added the option to use the system provided Emscripten toolchain to be more uniform with other libraries.

Fixed and issue which prevented example being built from cmake and also building with html extensions properly.

* Fixed ENUM to STRING because of a missed warning

/**********************************************************************************************
*
* raylib.core - Basic functions to manage windows, OpenGL context and input on multiple platforms
*
* PLATFORMS SUPPORTED:
* - PLATFORM_DESKTOP: Windows (Win32, Win64)
* - PLATFORM_DESKTOP: Linux (X11 desktop mode)
* - PLATFORM_DESKTOP: FreeBSD, OpenBSD, NetBSD, DragonFly (X11 desktop)
* - PLATFORM_DESKTOP: OSX/macOS
* - PLATFORM_ANDROID: Android 4.0 (ARM, ARM64)
* - PLATFORM_RPI: Raspberry Pi 0,1,2,3,4 (Raspbian)
* - PLATFORM_DRM: Linux native mode, including Raspberry Pi 4 with V3D fkms driver
* - PLATFORM_WEB: HTML5 with asm.js (Chrome, Firefox)
* - PLATFORM_UWP: Windows 10 App, Windows Phone, Xbox One
*
* CONFIGURATION:
*
* #define PLATFORM_DESKTOP
* Windowing and input system configured for desktop platforms: Windows, Linux, OSX, FreeBSD, OpenBSD, NetBSD, DragonFly
* NOTE: Oculus Rift CV1 requires PLATFORM_DESKTOP for mirror rendering - View [rlgl] module to enable it
*
* #define PLATFORM_ANDROID
* Windowing and input system configured for Android device, app activity managed internally in this module.
* NOTE: OpenGL ES 2.0 is required and graphic device is managed by EGL
*
* #define PLATFORM_RPI
* Windowing and input system configured for Raspberry Pi i native mode (no X.org required, tested on Raspbian),
* graphic device is managed by EGL and inputs are processed is raw mode, reading from /dev/input/
*
* #define PLATFORM_WEB
* Windowing and input system configured for HTML5 (run on browser), code converted from C to asm.js
* using emscripten compiler. OpenGL ES 2.0 required for direct translation to WebGL equivalent code.
*
* #define PLATFORM_UWP
* Universal Windows Platform support, using OpenGL ES 2.0 through ANGLE on multiple Windows platforms,
* including Windows 10 App, Windows Phone and Xbox One platforms.
*
* #define SUPPORT_DEFAULT_FONT (default)
* Default font is loaded on window initialization to be available for the user to render simple text.
* NOTE: If enabled, uses external module functions to load default raylib font (module: text)
*
* #define SUPPORT_CAMERA_SYSTEM
* Camera module is included (camera.h) and multiple predefined cameras are available: free, 1st/3rd person, orbital
*
* #define SUPPORT_GESTURES_SYSTEM
* Gestures module is included (gestures.h) to support gestures detection: tap, hold, swipe, drag
*
* #define SUPPORT_MOUSE_GESTURES
* Mouse gestures are directly mapped like touches and processed by gestures system.
*
* #define SUPPORT_TOUCH_AS_MOUSE
* Touch input and mouse input are shared. Mouse functions also return touch information.
*
* #define SUPPORT_SSH_KEYBOARD_RPI (Raspberry Pi only)
* Reconfigure standard input to receive key inputs, works with SSH connection.
* WARNING: Reconfiguring standard input could lead to undesired effects, like breaking other running processes or
* blocking the device is not restored properly. Use with care.
*
* #define SUPPORT_MOUSE_CURSOR_NATIVE (Raspberry Pi and DRM only)
* Draw a mouse pointer on screen
*
* #define SUPPORT_BUSY_WAIT_LOOP
* Use busy wait loop for timing sync, if not defined, a high-resolution timer is setup and used
*
* #define SUPPORT_HALFBUSY_WAIT_LOOP
* Use a half-busy wait loop, in this case frame sleeps for some time and runs a busy-wait-loop at the end
*
* #define SUPPORT_EVENTS_WAITING
* Wait for events passively (sleeping while no events) instead of polling them actively every frame
*
* #define SUPPORT_SCREEN_CAPTURE
* Allow automatic screen capture of current screen pressing F12, defined in KeyCallback()
*
* #define SUPPORT_GIF_RECORDING
* Allow automatic gif recording of current screen pressing CTRL+F12, defined in KeyCallback()
*
* #define SUPPORT_COMPRESSION_API
* Support CompressData() and DecompressData() functions, those functions use zlib implementation
* provided by stb_image and stb_image_write libraries, so, those libraries must be enabled on textures module
* for linkage
*
* #define SUPPORT_DATA_STORAGE
* Support saving binary data automatically to a generated storage.data file. This file is managed internally.
*
* DEPENDENCIES:
* rglfw - Manage graphic device, OpenGL context and inputs on PLATFORM_DESKTOP (Windows, Linux, OSX. FreeBSD, OpenBSD, NetBSD, DragonFly)
* raymath - 3D math functionality (Vector2, Vector3, Matrix, Quaternion)
* camera - Multiple 3D camera modes (free, orbital, 1st person, 3rd person)
* gestures - Gestures system for touch-ready devices (or simulated from mouse inputs)
