Unix Pageant is in a tricky position as a hybrid CLI/GUI application.
It has uses even in a purely CLI environment, but it won't build
without libgtk-3-dev and friends.
The solution, of course - enabled by the migration to cmake - is to
allow it to build without GTK, leaving out just the GTK askpass
functionality. That way you can still use it in any of its CLI modes,
either as a non-graphical SSH agent or as a client for an agent
elsewhere.
(You can still even use it in X lifetime mode, because its connection
to the X server is done using PuTTY's built-in X authentication and
connection setup code. It's only putting up the password prompt window
that you lose in this configuration - so you're still fine as long as
you don't try to add any encrypted keys.)
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
