    meson.build: Consolidate items with MSVC-like compilers
    
    Add a variable in meson.build that covers Visual Studio-like compilers,
    so that we can use it to help us find depedencies using CMake rather
    than via pkg-config, where applicable.
    
    Change the existing use case for finding libpng accordingly.
