    meson.build: Fix library search error messages
    
    The .format(...) items are placed wrongly in the cases that the required
    -mm libraries are not found.  Fix this.
    
    Make these messages clearer to people that all 3 C++-17 versions of the
    cairomm, glibmm and sigc++ .lib's are required by combining the 3
    assert messages into a single assert message.
