It's been a long while, so I wanted to get back to your patch.
Unfortunately, it doesn't build properly:

-- Checking for module 'freerdp>=1.0'
--   Found freerdp, version 1.2.5-dev
CMake Error at /home/test/buildroot/output/host/usr/share/cmake-3.4/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find FREERDP (missing: FREERDP_LIBRARY)
Call Stack (most recent call first):
  /home/test/buildroot/output/host/usr/share/cmake-3.4/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  cmake/FindFREERDP.cmake:47 (find_package_handle_standard_args)
  cmake/FindOptionalPackage.cmake:37 (find_package)
  remmina-plugins/CMakeLists.txt:59 (find_suggested_package)

It might be due to the fact that we updated freerdp in the mean time,
I'm not sure. You can reproduce this failure by building the following
configuration:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y

Since you also select some X11 library, I guess this package will only
work with the X11 backend of GTK3, so presumably, you need:

	depends on BR2_PACKAGE_LIBGTK3_X11

Is LIBSSH really mandatory? CMake says:

-- Finding suggested package LIBSSH.
--   Disable this using "-DWITH_LIBSSH=OFF".

Is gettext really mandatory ? CMake says:

-- Finding suggested package Gettext.
--   Disable this using "-DWITH_GETTEXT=OFF".
-- Found Gettext: /home/test/buildroot/output/host/usr/bin/msgmerge (found version "0.19.7")

We now would like to have hash files even for github sourced packages.
So if you could add a hash file, it would be good.

I think the package should rather use the FindIntl() function provided
by CMake, see https://cmake.org/cmake/help/v3.3/module/FindIntl.html,
by doing:

find_package(Intl)

This is probably something you can bring upstream to the Remmina
developers. In the mean time, we can live with the $(SED) hack you
proposed.

Could you rework the patch to address the various comments, and send an
updated version?

Thanks!

Thomas
