winpr is now always build as single library.
The build option MONOLITHIC_BUILD doesn't influence this behavior anymore.
The only exception is winpr-makecert-tool which is still build as extra
library.
This obsoletes complex_libraries for winpr.
The X11 core protocol does not have support for selection ownership
notifications. Until now xfreerdp worked around this issue by always sending
a format list pdu to the server after sending the format data response pdu
which makes the server side think that the clients clipboard data has changed.
This workaround has some severe drawbacks:
* it causes unnecessary data transfers because even without local clipboard
data changes the same data is always re-transferred over the channel
* with some clipboard managers (in the server sessions) you will get massive
endless data transfer loops because these managers immediately request the
data on clipboard changes.
The correct (core X11) way would be polling for selection ownership changes
which must include the ability to detect changes to the TIMESTAMP target if
the selection owner did not change.
The alternative to the poll based approach is using the X Fixes extension in
order to get selection ownership notifications.
This commit adds support for the XFIXES solution and also moves the complete
clipboard related event handling from xf_event.c to xf_cliprdr.c
with current date.
Added CMake script to generate a variable containing the current
date.
Removed last argument (the terminating NULL element) from output.
To check if something should be en- or disabled WITH_XXX
should be used and not XXX_FOUND.
If XXX_FOUND is used and something gets disabled afterwards (by setting
WITH_XXX to OFF) it will be compiled in as long as XXX_FOUND is found in
cmake's cache file. So disabling a feature, or option, without
clearing the CMakeCache.txt might result in builds with unwanted
configuration.
