Some applications might check for PLATFORM_WEB instead of __EMSCRIPTEN__.

Removed clutter.

Removes a warning that linker-only flags were being passed to the compiler, which is in accordance to https://emscripten.org/docs/tools_reference/settings_reference.html.

Makes use of the new functionality found in ParseConfigHeader.cmake to make things consistent.

This script parses the config.h file to automate the process of exposing the configuration flags and configuration values found in the latter.

* Fix several non-functional `target_compile_definitions`

* Avoid hardcoding the default vertex attribute locations

* Implement functional `rlNormal3f`

* Add normal definitions for `DrawCube`

* Update the basic lighting example to use `DrawCube` and `DrawPlane`

* CMake: Remove USE_WAYLAND option

* Consistency fix

* Fix oversight

* Update GLFW to 3.4 (draft)

* Add _glfwConnectNull() function to rglfw.c

* Update rglfw.c

* Update Makefile

* Makefile: Replace USE_WAYLAND_DISPLAY with DISABLE_WAYLAND

* Revert "Makefile: Replace USE_WAYLAND_DISPLAY with DISABLE_WAYLAND"

This reverts commit 9e79abde78.

* GlfwImport.cmake: Replace GLFW_USE_WAYLAND with GLFW_BUILD_WAYLAND

* Update rglfw.c

* Output platform selected by GLFW to TRACELOG

* GLFW has removed Mir support

I broke this in PR #3573 by accidentally removing too much
The examples still compiled fine so I didn't notice - my guess is that
cmake was still adding a separate link to glfw manually.

* Remove PLATFORM_RPI

* remove build artifacts

Closes #3265.

The problem: LIBS_PRIVATE is a list of library names (used by pkg-config), but the shared library of the same name doesn't always exist.

* Fixed compile on OpenBSD

* Changed to not use seperate UNIX for cmake

* OpenGLES 2.0 support on PLATFORM_DESKTOP

* exmples raylib_opengl_interop desktop GLES2 support

* rename gles2.h -> glad_gles2.h

Use GLVND also when legacy implementations exist for old cmake versions
<= 3.10. This is a breaking change for old cmake versions (prior to
around 2017-10-05) which will now use GLVND rather than defaulting to
libGL.

This fixes the following warning when building:

    CMake Warning (dev) at /gnu/store/qv13zgbmyx0vjav8iiqp772kp6rxvwnd-cmake-3.24.2/share/cmake-3.24/Modules/FindOpenGL.cmake:315 (message):
      Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when
      available.  Run "cmake --help-policy CMP0072" for policy details.  Use the
      cmake_policy command to set the policy and suppress this warning.

      FindOpenGL found both a legacy GL library:

        OPENGL_gl_LIBRARY: /home/simendsjo/.guix-profile/lib/libGL.so

      and GLVND libraries for OpenGL and GLX:

        OPENGL_opengl_LIBRARY: /home/simendsjo/.guix-profile/lib/libOpenGL.so
        OPENGL_glx_LIBRARY: /home/simendsjo/.guix-profile/lib/libGLX.so

      OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
      compatibility with CMake 3.10 and below the legacy GL library will be used.
    Call Stack (most recent call first):
      cmake/LibraryConfigurations.cmake:21 (find_package)
      src/CMakeLists.txt:46 (include)
    This warning is for project developers.  Use -Wno-dev to suppress it.

See https://cmake.org/cmake/help/latest/policy/CMP0072.html

Closes #2825

Those functions were platform dependent and user has no control over the file created. They have been removed from raylib and just moved to `core_storage_values` example.

`android_native_app_glue.c` wasn't appended to the `raylib_sources` as other libraries were.

Updated cmake to windows users.
So they can `find_package(raylib [...])` with exported target as raylib instead of ${raylib_LIBRARIES}, etc

This fixes compilation and linking errors when CUSTOMIZE_BUILD is
ON. Any option wasn't actually applied if it wasn't in this list.

I also added a message which makes it a bit easier to confirm you have
successfully enabled an option.

* Fixed Compiling Raylib for android Using cmake

* improved the cmake config for android so it don't conflict

* improved the cmake config for android so it don't conflict

* Add find opengl for widnows too.

* Also fix set LIBS_PRIVATE to bi similar to linux and apple targets

* Log a warning if chdir failed, use agnostic CHDIR instead of chdir

* Only include libdrm directory explicitly when not cross compiling

* Update CMakeOptions.txt

* Update config.h.in

* Added SUPPORT_STANDARD_FILEIO to CMakeOptions.txt

* Fixed typo

* Added SUPPORT_STANDARD_FILEIO to CompileDefinitions.cmake

* Documenting the compiler flags

* Moved some android compiler flags and added documentation on them too.

* Some more restructuring.

Removed unnecessary comments that were self described by the code.
Added some more explanations around certain parts of CMake and especially around compiler flags.

CMake relied on this file for configurations and also was interfering in the regular config.h by having a separate definition if building with CMake. This was not entirely correct so instead we will define compile time definitions separately through CMake (CompileDefinitions.cmake) and also will use the provided EXTERNAL_CONFIG_FLAGS that I found that will not use config.h in through the build process.

I also introduced a new compiler option (CUSTOMIZE_BUILD) that when OFF will use the default config.h and when ON will show other options for redefining your own options.

Fixed an error in rlgl.h where if you have both RLGL_STANDALONE and SUPPORT_VR_SIMULATOR you get a compile time error.

This test file is just testing compilation with the library works correctly but is no longer needed because:
- it is not cross platform
- it taps into the CTest system which is better suited for real unit/integration tests
- it can be incorporated into the pipeline of github actions instead in the future

As described in the official documentation https://cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html this flag is global by default and controls if the library will be built as a shared or a static library allowing us to define only one call to the add_library function (without specifying its type). It is also added as an option to be visible in CMake GUI applications.

* Delete emscripten.cmake

This file is not needed at this point. EMSDK provides a toolchain file that has a lot more things in it and is better supported. Project currently works fine with the documentation provided in Emscripten SDK on how to build projects.

* First pass file separation.

The main two files are cleaner now. Only important things can be seen. Major changes include:
- raylib_static is now the alias instead of raylib
- Repeating segments are removed and pulled into separate files into <root>/cmake
- File is reordered to make more sense
- Installs are better structured
- Library is build into an output directory "raylib" instead of "src"
- All public header files are now set as a public header file
- Source files need to be listed (it is a bad practice to capture them using wildcards and file globs)
- CMakeLists are better commented

* Second pass on the example dirs.

They are quite complex so I'm more hesitant to do major changes. Also it works pretty well. Noticed that I forgot one of the seperated files and added it into src/CMakeLists.txt.

* Returned the header copy as it was convenient to have the public headers copied.

* A better description to the variable RAYLIB_IS_MAIN
