 put pkg-config command into a variable
 When cross-compiling on debian, the build system dh set the name of the
 pkg-config command name to use into PKG_CONFIG variable.
 For armhf, it is PKG_CONFIG=arm-linux-gnueabihf-pkg-config
 .
 Since the pkg-config that is installed during cross-compiling is the one
 of the build-arch (amd64), and not the one of the host-arch (armhf),
 using `pkg-config` instead of `arm-linux-gnueabihf-pkg-config` would
 prevent detection of the libraries.
 .

 main patch to compile on debian & derivatives
 - Set the path to the resource dir on Debian
 . remove the "arch" name from the produced executable name.
 - update compilation flags:
    - CPPFLAGS: required because it is set in debian/rules
    - LDFLAGS: remove -s because stripping this is done in dh_strip. If we
      kept it, the dbgsym packages would be almost empty.
    - LDFLAGS: remove -no-pie because this would conflict with
      DEB_BUILD_MAINT_OPTIONS set in debian/rules. The value hardening=+all
      enables PIE, while -no-pie would conflit with that.

 remove upstream's `-o3` build optimization
 This permits to build with Debian's default optimization which are set through
 buildflags.mk
 .
 With this, usually it will build with -O2.
 .
 Using this mechanism also permits to honor the DEB_BUILD_OPTIONS=noopt in
 which case, optimization is set to -O0.
 .

 build with gtk3 instead of gtk2
 - wxwidgets is built with gtk3, so we have to build with gtk3
 - add the LDFLAGS for gtk+-3.0, otherwise, the build would fail with:
 .
 /usr/bin/ld: /tmp/cc6adrRa.ltrans115.ltrans.o: undefined reference to symbol 'gtk_css_provider_load_from_path'
 /usr/bin/ld: /lib/x86_64-linux-gnu/libgtk-3.so.0: error adding symbols: DSO missing from command line
 .
 "::gtk_css_provider_load_from_path" is called in
   FreeFileSync/Source/application.cpp
   FreeFileSync/Source/RealTimeSync/application.cpp

 add missing ldflags & cxxflags of zlib
 - zlib's deflate() is used in zen/zlib_wrap.*
 .
 - update compilation flags:
    - CXXFLAGS: add flags for zlib
    - LDFLAGS: add flags for zlib
 .
 Since ffs calls the deflate function of zlib in zen/zlib_wrap.*, we have to
 add -lz.
 .
 Otherwise build would fail this way:
  /usr/bin/ld: /tmp/FreeFileSync_Make/ffs/src/../../zen/zlib_wrap.cpp.o: undefined reference to symbol 'deflate'
  /usr/bin/ld: /lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
 .
 The RealTimeSunc binary doesn't use zen/zlib_wrap.*, so it is not required in
 that case.
 .
 Required since 10.0
 .

 permit reproducible builds by use of source_date_epoch
 Currently the code relies on __DATE__ and __TIME__ macros.
 .
 This prevents to have reproducible build because these values changes every
 time we compile.
 .
 To achieve reproducible builds, make use of SOURCE_DATE_EPOCH as proposed
 on https://reproducible-builds.org
 .
 See:
  - https://reproducible-builds.org/docs/
  - https://reproducible-builds.org/docs/source-date-epoch/

 add values from missing constants taken from libssh2
 The upstream author observed that some of the values he uses are not in the
 libssh2 public headers. I don't know where he uses them from, but I had to
 replace them here to get this to compile.

 solve syntax issue when using libglib2 >= 2.67
  Preprocessor output for `::g_object_ref(gicon); ` is:
      ::((typename std::remove_reference<decltype (gicon)>::type) (g_object_ref) (gicon));
  Since commit https://gitlab.gnome.org/GNOME/glib/-/commit/5b2bee3f539056b42c802608f9f00cc9ddd64b79
  that is shipped starting from 2.67.0, the macro g_object_ref changed and is
  also defined when __cplusplus is defined in some circumstances.
 .
  Removing the scope resolution operator `::` permits the code to build.
  There remains to check whether this is the correct fix.

 don't process the missing animal.dat image
 Upstream doesn't ship the Animal.dat file in the sources. It is a picture
 that is displayed in the "About" window.
 .
 Remove the display of that picture and resize the widgets so as to occupy
 all the space freed by it.

 disable wxwidgets uncaught exception handling
 wxWidgets' exception handling gets in the way of debugging by
 handling uncaught exceptions, thous hiding their point of origin.
 This causes the build to fail:
 application.cpp:249:2: error: #error why is wxWidgets uncaught exception handling enabled!?
  249 | #error why is wxWidgets uncaught exception handling enabled!?
      |  ^~~~~
 compilation terminated due to -Wfatal-errors.

 deactivate google drive
 Upstream doesn't ship the client_id & client_secret that are required to
 interact with Google's servers.
 .
 This results in failures like the one described here:
 .
    https://freefilesync.org/forum/viewtopic.php?t=11054
 .
 This patch:
  - disables the Google Drive button in the UI
  - displays the UI elements for sftp when opening the 'Cloud' dialog (instead
  of those for Google Drive).
 .
 Required since 10.9

 Applied since 13.3-2

 extend the versions of libcurl that can be used to build ffs
 .
 Minimal version supported by this patch is libcurl >= 7.66
 .
 FreeFileSync makes an 'assert' that it supports all error codes of the curl
 version that it links to. Since FreeFileSync code is shipped to build
 with a specific version of curl, there is a hard coded assertion.
 .
 To avoid a build failure when curl is not in line with the one used upstream
 we make conditional checks on the curl version to determine which assertion
 should be made.
 .
 While this works fine to build with any old version of curl > 7.66, there
 will be a build fairure as soon as a new error code appears in a newer version
 of curl. In that case it is required to add it here.
 .
 Error codes can be found in the 'enum' named 'CURLcode' at
 https://github.com/curl/curl/blob/master/include/curl/curl.h
 .
