   WINDOWS

copy yasm*.exe (http://yasm.tortall.net/Download.html - "for general use on 64-bit Windows") into:
C:\Esenthel\ThirdPartyLibs\VP\Windows32\yasm.exe
C:\Esenthel\ThirdPartyLibs\VP\Windows64\yasm.exe

In Cygwin Terminal:

Windows 32/64/Arm Cygwin
cd /cygdrive/c/Esenthel/ThirdPartyLibs/VP/Windows32
../libvpx/configure --target=x86-win32-vs15 --enable-static-msvcrt --disable-examples --disable-tools --disable-docs --disable-unit-tests --disable-spatial-resampling --enable-runtime-cpu-detect --disable-vp8 --disable-vp9-encoder

make

For all 32/64/ARM open the VS project
-Don't do this:
	we could include "webmdec.cc" and "third_party/libwebm/mkvparser.cpp" files in the "vpx" project, however that would require making a separate WindowsUniversal libs for 32/64 because of MultiThreaded/MultiThreadedDLL conflict, instead, these files are included in the Engine Video.cpp file
-edit project:
	C/C++
		General \ Debug Information Format = None
		Optimization \ Whole Program Optimization = NO
ON ARM PROJECT ONLY:
	General
		Target Platform Version 10.0.15063.0
		Target Platform Min. Version 10.0.15063.0
-build "vpx" in Release

   ANDROID

CygWin fails, so we have to use Mac Terminal:

ANDROID ARM 32

cd /Esenthel/ThirdPartyLibs/VP
rm -r temp
mkdir temp
mkdir temp/jni
cp -r libvpx temp/jni/libvpx

ANDROID x86

Yasm
On Mac need to install yasm (nasm didn't work, even after upgrading)
-download yasm and extract
-enter with terminal
./configure
make
sudo make install

HAVE TO EDIT VP/libvpx/vpx_ports/x86_abi_support.asm because there's linking error for 'rand'
replace:
%ifdef __ANDROID__
with
%if 1

copy to Windows folder "VP/Android/"
on windows run "extract.bat"

   Mac 64

First install Yasm as described above for Android

cd /Esenthel/ThirdPartyLibs/VP/Mac
../libvpx/configure --target=x86_64-darwin13-gcc --disable-examples --disable-tools --disable-docs --disable-unit-tests --disable-spatial-resampling --enable-runtime-cpu-detect --disable-vp8 --disable-vp9-encoder
make
remove all other generated files as they may cause invalid compilation for other targets

   iOS

cd /Esenthel/ThirdPartyLibs/VP/Mac
../libvpx/configure --target=armv7-darwin-gcc --disable-examples --disable-tools --disable-docs --disable-unit-tests --disable-spatial-resampling --enable-runtime-cpu-detect --disable-vp8 --disable-vp9-encoder
make
mv libvpx.a libvpx_armv7.a
remove all other generated files as they may cause invalid compilation for other targets

cd /Esenthel/ThirdPartyLibs/VP/Mac
../libvpx/configure --target=arm64-darwin-gcc --disable-examples --disable-tools --disable-docs --disable-unit-tests --disable-spatial-resampling --enable-runtime-cpu-detect --disable-vp8 --disable-vp9-encoder
make
mv libvpx.a libvpx_arm64.a
remove all other generated files as they may cause invalid compilation for other targets

   Once Mac and iOS are ready on Windows, copy the entire VP folder to Mac.

/******************************************************************************/

   Linux 64

install yasm first using:
sudo apt-get install yasm

cd ~/Esenthel/ThirdPartyLibs/VP/Linux
../libvpx/configure --target=x86_64-linux-gcc --disable-examples --disable-tools --disable-docs --disable-unit-tests --disable-spatial-resampling --enable-runtime-cpu-detect --disable-vp8 --disable-vp9-encoder
make
copy entire folder to Windows without deleting any files (both *.a and *.o are needed)

/******************************************************************************/

	5. Don't forget to run "Finish.bat" !!
