libVPL build instruction

• If you don’t have libVPL dispatcher, you will need to build it manually

  $ git clone https://github.com/intel/libvpl.git

  $ cd libvpl

  $ mkdir build

  $ cd build

  $ cmake ..

• Open vpl.sln using Visual Studio in your build file.

• Choose Release build at the top. Then find vpl solution and right click to build.

• After build finishes, you will get vpl.lib and libvpl.dll in libvpl/build/Release

• Find vpl.pc in libvpl/build/dispatcher/pkgconfig

• Modify vpl.pc using absolute path. Make sure compiler can find vpl.lib in libdir and headers in includedir. For example

  libdir=C:/msys64/home/username/libvpl/build/Release

  includedir=C:/msys64/home/username/libvpl/api/vpl

  Note: Following file path cannot be recognized by mingw64

  libdir=C:\msys64\home\username\libvpl\build\Release
