The build file builds Raylib as a static library for either
Windows or Linux.

This reverts commit 4a01139c8d.

When building a shared Raylib library on Linux, the build process
produces 3 files: libraylib.so (symlink), libraylib.so.381 (symlink)
and libraylib.so.3.8.1 (the library).

Only the first one of these (.so) is currently ignored by Git.
Adding *.so.* to .gitinore makes Git ignore the rest of them as
well.

* Fix Makefile to build WASM examples.

- Add --preload-file flag before specifying the resource dir
- Add empty resource dir to `shapes/` (otherwise wasm-ld will fail)
- Add wasm outputs to .gitigore

* Delete .gitignore

* Added support for additional mouse buttons

* Renamed mouse button enum

Co-authored-by: Lambert Wang <lambert.ww@gmail.com>

* Better ignore support for idea projects.

Added a wildcard at the end because different configurations would have a diffeerent build directory.

* Removed external from being a relative include directory for target raylib.

Fixes #1533

As noted in #539, the symlink check was to support compiling raylib on
VirtualBox vboxfs as no symlinks are supported there.

With me using Linux as daily driver outside VirtualBox now, this 'feature'
is most likely unused by anyone, but still annoys other users (#791).
Just revert it and be done with it. If there are really others building
raylib on vboxfs or a similarly crippled file system under Linux, they
should now step forward when their build breaks.

This reverts commit b8ca51fd01.

* new linux makefile for Android portages

* Revert "projects: CMake: bump up minimal raylib version (#983)"

* new PR for upstream

* for Raysan

* Working build

* Fix build again, stop deleting files

* Hotfix crash, needs investigating

* Remove VS2015.UWP, I cannot update the project

* Lots of UWP work, added keyboard and mouse press support. Still need to finish scroll wheel, mouse position and cursor hiding, plus other stuff that I haven't seen yet.

* Implemented a ton more things, added BaseApp.h to provide common code to UWP apps.

* Remove constant window dimensions

* Enable and Disable cursor support.

* Actually use mouse delta

* Gamepad Support

* Cleaning and small tweaks

* Restore original example.

* Update comment

* Use 'Messages' to handle the cursor functions so code is more portable.

* Comment

* Comment unused message fields and use vector for mouse pos instead.

* Move messages to utils.h and use messages for everything. No more plat-specific code in raylib.h

Review raylib_icon resource

Panders to the idiosyncrasies of my work flow:
I have my raylib build directory mounted as a VirtualBox vboxfs for use
with my Linux VM, but vboxfs doesn't support symlinks, while raylib shared
library versioning on Unix expects symlinks to work.
If this happens, library versioning is now disabled on Unix with
an error message instead of just failing the build.

Less maintenance overhead that way,
given that make/CMake now also do library versioning.

They were disabled because they failed to build,
but this patch set fixes the build on Linux and macOS.

This doesn't apply to the AppVeyor build on Windows yet;
it currently fails at linking with OpenAL.

Support Universal Windows Platform (UWP):
- Windows 10 App
- Windows Phone
- Xbox One

OpenAL Soft and raylib compiled for release and stripped

Some people might find this handly

Added loader webs (previously ignored)
