The API and ABI isn't as stable as we need, so it isn't safe to
link it dynamically even on Linux.

Change Xserver screen through libXrandr. For complex configurations,
all outputs must have corresponding size modes. As a special case, if
the client requests a single screen with an odd size (for example when
adjusting the size of a non-fullscreen vncviewer), find a smaller
suitable mode, and reduce the framebuffer size as well.

Newer versions of Freetype requires libpng as well.

Useful for debugging memory leaks and access violations. It is
not available on Windows though, and there is some problem compiling
ObjectiveC++ with it turned on.

Need to explicitly list DSOs.

We're not doing a sufficient job of keeping this updated so list
it as an external requirement instead.

GnuTLS may be compiled without external libtasn1, so we shouldn't try
to link against it unless it's actually present.

Needed to merge upstream changes in before creating pull request.

GnuTLS may be compiled without external libtasn1, so we shouldn't try
to link against it unless it's actually present.

Our link order should now match the built-in library list.

Static builds are the special case, so it should be left off
by default.

This is needed to make sure they are always included, and in the
proper order.

crypt32 is a Windows thing, and it is used no matter the crypto
backend.

CMake is very aggressive about minimising the list of libraries,
so we need to be similarily aggressive about quotes to make sure
we get everything we want and in the correct order.

Commit f95272d created some undefined references in GnuTLS.

Try to link as much as possible statically in an effort to produce
binaries that can be run everywhere.
