DEVELOPER_MODE is designed for various developer issues. Now this mode
forced to use plugins only from build tree. To avoid excess plugins
from system QCA. Also now not need to set QT_PLUGIN_PATH to use plugins
from QCA build tree.
Now possible to build only required plugins and skip all others.
Also can get fail if required plugins can't be built.
By default will be build all possible plugins.
New cmake cache variables:
ENABLE_PLUGINS - list plugins to build (botan;ossl;gnupg for example).
Also possible values is none, auto or all
(by default: "auto")
WITH_${PLUGIN}_PLUGIN - to build particular plugin. Can be no, yes or
auto (WITH_ossl_PLUGIN=auto for example)
This cache entry dropped. Now Qt prefix will be used only
if user explicity don't define CMAKE_INSTALL_PREFIX.
Also show attention for user if he didn't define CMAKE_INSTALL_PREFIX
make installwin.bat regenerate crypto.prf at install time, mainly for
consistency with qca binary packages
