dnl This is ugly and complicated. Yuck. Works as follows:
dnl We can't discern whether Qt4 builds are static or not. For Qt5, we can
dnl check a header to find out. When Qt is built statically, some plugins must
dnl be linked into the final binary as well. These plugins have changed between
dnl Qt4 and Qt5. With Qt5, languages moved into core and the WindowsIntegration
dnl plugin was added. Since we can't tell if Qt4 is static or not, it is
dnl assumed for windows builds.
dnl _BITCOIN_QT_CHECK_STATIC_PLUGINS does a quick link-check and appends the
dnl results to QT_LIBS.
