Building examples by default only if raylib is standalone. (#1460) This change only modifies the default value. In cmake you can have raylib as a subdirectory (dependency) and when you have it as dependency you wouldn't probably want to use the example by default. You can still use the option to enable them though.

option(ENABLE_ASAN "Enable AddressSanitizer (ASAN) for debugging (degrades performance)" OFF)
option(ENABLE_UBSAN "Enable UndefinedBehaviorSanitizer (UBSan) for debugging" OFF)
CMake: Major cleanup to support find_package(raylib) Remove that link_libraries_to_executable() hack and defines a proper raylib target that can be used with target_link_libraries. The same target is also available for external (user) code by using find_package(raylib). This results in: - Remove hardcoded build directories from examples and games CMakeLists.txt - Allow rlgl_standalone and other special examples to be built easily - Allow CMake projects to find_package(raylib instead of fiddling with pkg-config - Makes code a little more maintainable - Fixes #471, #606. - Makes code less confusing by removing the double use of PLATFORM (#584). Note that this is still not _The Right Way_(TM), because normally raylib-config.cmake (or its includes) would be automatically generated. I didn't manage to get that to work though, so I went the easier route of just wrapping pkg_check_modules for consumption by find_package.

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

# This helps support the case where emsdk toolchain file is used
# either by setting it with -DCMAKE_TOOLCHAIN_FILE=<path_to_emsdk>/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake

CMake: Explicitly ask for C99 support Otherwise using a compiler that defaults to -std=c89 or -std=gnu89 will fail. Example: http://www.cpantesters.org/cpan/report/abb85066-d283-11e7-9926-b2f4efb9c382 Apparently, -m32 Travis CI build was broken: -m32 was overridden by -std=gnu99. This fixes that.

jar_xm: Workaround for unaligned pointer accesses jar_xm.h does some shady pointer casts leading to unaligned accesses and breaking strict aliasing. x86 has special circuitry for doing unaligned accesses, but on other architectures, it may trap and require kernel fix-up or crash outright. With this patch, one obstacle in porting raylib to the GameBoy Advance has been removed. Go for it ;-) To avoid having to rewrite that `mempool' code, insert padding before structs and instruct the compiler (GCC, most importantly), to be gentle when optimizing. This fixes #490 (Unless we got ourselves 256-bit pointers, if so, hello future!)
