Setting up the dependencies for compiling on Windows.

Move and rename the files as required for matching the paths in CMakeLists.txt

Visual Studio Community 2015

https://go.microsoft.com/fwlink/?LinkId=691978&clcid=0x409

• Select: Programming Languages > Visual C++ > Common Tools for Visual C++ 2015
• Unselect everything else including the other Visual C++ features

CMake

https://cmake.org/download/ > cmake-3.5.1-win32-x86.msi

• There's no 64-bit version for Windows.

FreeType

https://sourceforge.net/projects/freetype/ > ft263.zip (2.6.3)

• Open the CMake GUI and browse to the source.
• Use default native compilers
• Source: ft263/freetype-2.6.3
• Build: ft263/freetype-2.6.3/builds
• Click Configure
• Specify the generator for this project > Visual Studio 14 2015 Win64
• Ignore error: "Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)"
• Click Generate
• Open freetype-2.6.3\builds\freetype.sln
• Solution Configurations > Release
• Build > Build Solution

GLFW

http://www.glfw.org/download.html > 64-bit Windows binaries

• Move:

From	To
glfw-3.1.2.bin.WIN64	dynagann\libraries\win64\glfw-3.1.2
.lib and .dll files from lib-vc2015	to parent (glfw-3.1.2) dir

cppformat

https://github.com/cppformat/cppformat/releases > 2.1.0

• Same procedure as with FreeType for generating the 64-bit VS project files
• Open libraries\win64\cppformat-2.1.0\build\FORMAT.sln
• Right click Solution "FORMAT" > Retarget solution
• Solution Configurations > release
• Right click "cppformat" > Build
• Move:

\libraries\win64\cppformat-2.1.0\build\cppformat\Release\cppformat.lib -> \libraries\win64\cppformat-2.1.0\cppformat\cppformat.lib

Newton Dynamics

https://github.com/MADEAPPS/newton-dynamics/releases > 3.1.3

• Don't use the CMake build, it doesn't work on Windows.
• Open packages\projects\visualStudio_2013_dll\build.sln
• As explained in http://newtondynamics.com/forum/viewtopic.php?f=12&t=8881:
  • Add a preprocessor define of HAVE_STRUCT_TIMESPEC in the pthread project properties
  • In coreLibrary_300\source\core\dgTypes.h add:

#ifdef _MSC_VER 
   #ifdef _M_X64
      #ifndef _WIN_64_VER
         #define _WIN_64_VER
      #endif
   #else       
      #ifndef _WIN_32_VER
         #define _WIN_32_VER
      #endif
   #endif

   // ADD THIS PART
   #if _MSC_VER >= 1400
      #define HAVE_STRUCT_TIMESPEC
   #endif
#endif

Move:

From	To
libraries\win64\newton\coreLibrary_300\projects\windows\project_vs2013_dll\x64\newton\release\newton.lib	libraries\win64\newton\lib\newton.lib
libraries\win64\newton\coreLibrary_300\projects\windows\project_vs2013_dll\x64\newton\release\newton.dll	dynagann\bin

Boost

https://sourceforge.net/projects/boost/ > 1.60.0 bootstrap.bat b2.exe address-model=64

glm

https://github.com/g-truc/glm/releases > 0.9.7.4

• Same procedure as with FreeType for generating the 64-bit VS project files

GLEW

https://sourceforge.net/projects/glew/ > 1.13.0

Move:

From	To
bin\Release\x64\glew32.dll	dynagann\bin
lib\Release\x64\glew32.lib is the corresponding 64-bit lib.

glew32.dll is the 64-bit DLL despite the conflicting name.
