    Optionally locate boost via environment variable BOOST_ROOT
    
    This was already the case for our autotools based build
    and simplifies the build setup for our Windows build system.

commit 0a8d7a2142419c9494bf40324936a31b380d2161

    Make google test framework a mandatory build dependency
    
    All c++ unit tests will be written with it, and testing
    should be possible out of the box.
    We could make it optional, but then lots of tests will
    be skipped. This creates an illusion of all tests passing
    while many are simply not run. This confusion should be
    avoided.
    This change depends on a second commit for the windows build
    in the gnucash-on-windows repository. This commit will be
    pushed at the same time.
