        Hi,
to be honest, I did not notice any "program start parameters" you are
mentioning now, to be in the original post of this thread.

More importantly, you did not tell us *how* you build the Evolution.
You use CMake, of course, but that's far from the answer for the *how*.

Anyway, the Edit->Plugin Manager is added as an
evolution-plugin-manager.so module. Maybe Evolution claims runtime
warnings on the console, or it doesn't load any module (if that's
true - you didn't tell us - then you may see an empty Evolution window.
I mean really empty, no Mail, no Contacts, no Calendar, ... just a gray
(depending on your theme) empty window), because Evolution cannot read
its plugins/modules or the libraries they want (it depends whether
there's a runtime warning hinting any such thing on the terminal of the
Evolution or not - you did not tell us).

Why is that so is the question. It can be that your CMAKE_INSTALL_DIR
doesn't match the place you install the files to (due to the DESTDIR
usage?). Do fix that and the things will work. From my point of view,
you misunderstand and misuse the DESTDIR variable. But I can be wrong,
in either or both statements. Again, anybody else using the DESTDIR
uses it successfully, only you have problem with it.

But really, follow the Building wiki page, from the top to the bottom,
and you'll get things working easily. If you are doing some magics
nobody has an idea of, then you are in it on your own. I'm sorry. Note
this is not about alternative build ways, you can build the software
the way it works the best for you. If you have issues, then try the
Building wiki page, check what you've done differently and try to find
out what you do wrong, because you surely do something wrong.

I mentioned it elsewhere, Evolution is a complex application. Do pick a
simpler application, with which you can get familiar with some basics
and advanced practices. Just my opinion.

        Bye,
        Milan
