Qt
--
You can download directly the binaries or compile yourself.
http://qt-project.org/downloads
My config (Qt 5.5.0):
Mac:
Download and install qt-opensource-mac-x64-clang-5.5.0.dmg or
./configure -release -opensource -confirm-license -static -no-sql-sqlite -no-sql-odbc -no-qml-debug -no-gif -no-nis -no-dbus -no-audio-backend -no-framework -nomake examples
Windows:
Edit qtbase\mkspecs\win32-msvc2013 and replace -MD by -MT in order to have  static build of the C++ library
Launch VS Tools Command Prompt 
configure -opensource -confirm-license -static -ltcg -no-sql-sqlite -no-sql-odbc -no-qml-debug -no-gif -no-dbus -no-opengl -no-audio-backend -no-freetype -nomake examples -mp
nmake

Qwt
---
Linux:
Launch VS Tools Command Prompt 
Add QT bin folder to your PATH e.g. set "PATH=%PATH%;C:\Qt\qtbase\bin"
Edit qwtconfig.pri, comment QwtDll, QwtSvg and QwtOpenGL lines
qmake
nmake

YASM
----
For Ffmpeg speed optimization, you need to install YASM
http://yasm.tortall.net/Download.html
My config (YASM 1.3.0):
Windows: I put the binary from website in /FFmpeg_for_QCTools directory, rename it to yasm.exe, FFmpeg automaticly detects it

Cmake
-----
For OpenJPEG compilation, install Cmake
My config (Cmake 3.0.0):
Download and install Cmake

OpenJPEG
--------
Download OpenJPEG 1.x (2.x is not supported by Ffmpeg)
My config (openjpeg 1.5.2):
Windows:
Launch VS Tools Command Prompt 
cmake Visual Studio 12 .
Edit libopenjpeg/openjpeg.vcxproj and replace MultiThreadedDLL by MultiThreaded in order to have  static build of the C++ library
Launch the sln, build release
Linux (static build):
cmake -DBUILD_SHARED_LIBS:BOOL=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=usr .
make
make install
Mac:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=usr .
make
make install

MSYS
----
Windows:
Install MSYS

FFmpeg
------
My config:
Windows:
Look at http://ffmpeg.org/platform.html#Windows
Launch VS Tools Command Prompt 
msys.bat
cd ffmpeg
./configure --enable-gpl --enable-version3 --enable-shared --disable-securetransport --disable-videotoolbox --disable-swscale-alpha --disable-doc --disable-ffplay --disable-ffprobe --disable-debug --toolchain=msvc
make
Copy *.lib in Project\MSVC2013\GUI\Lib
Mac:
./configure --enable-gpl --enable-version3 --enable-shared --disable-swscale-alpha --disable-doc --disable-ffplay --disable-ffprobe --disable-debug --enable-libopenjpeg --disable-decoder=jpeg2000 --yasmexe=../yasm/yasm --extra-cflags="-I../openjpeg/usr/include" --extra-ldflags="-L../openjpeg/usr/lib -mmacosx-version-min=10.8"
make
Linux (static build):
./configure --enable-gpl --enable-version3 --disable-shared --enable-static --disable-swscale-alpha --disable-doc --disable-ffplay --disable-ffprobe --disable-debug --enable-libopenjpeg --disable-decoder=jpeg2000 --extra-cflags="-I../openjpeg/usr/include" --extra-ldflags="-L../openjpeg/usr/lib"
make
