Merge PDF preview migration (replaced webserver with C++ rendering)

PDFs are now rendered in the texedit process as part of the GUI
for previewing.

+# --------------------
+#
+# Helper macros for find modules: ecm_find_package_version_check(),
+# ecm_find_package_parse_components() and
+# ecm_find_package_handle_library_components().
+#
+# ::
+#
+#   ecm_find_package_version_check(<name>)
+#
+# Prints warnings if the CMake version or the project's required CMake version
+# is older than that required by extra-cmake-modules.
+#
+# ::
+#
+#   ecm_find_package_parse_components(<name>
+#       RESULT_VAR <variable>
+#       KNOWN_COMPONENTS <component1> [<component2> [...]]
+#       [SKIP_DEPENDENCY_HANDLING])
+#
+# This macro will populate <variable> with a list of components found in
+# <name>_FIND_COMPONENTS, after checking that all those components are in the
+# list of KNOWN_COMPONENTS; if there are any unknown components, it will print
+# an error or warning (depending on the value of <name>_FIND_REQUIRED) and call
+# return().
+#
+# The order of components in <variable> is guaranteed to match the order they
+# are listed in the KNOWN_COMPONENTS argument.
+#
+# If SKIP_DEPENDENCY_HANDLING is not set, for each component the variable
+# <name>_<component>_component_deps will be checked for dependent components.
+# If <component> is listed in <name>_FIND_COMPONENTS, then all its (transitive)
+# dependencies will also be added to <variable>.
+#
+# ::
+#
+#   ecm_find_package_handle_library_components(<name>
+#       COMPONENTS <component> [<component> [...]]
+#       [SKIP_DEPENDENCY_HANDLING])
+#       [SKIP_PKG_CONFIG])
+#
+# Creates an imported library target for each component.  The operation of this
+# macro depends on the presence of a number of CMake variables.
+#
+# The <name>_<component>_lib variable should contain the name of this library,
+# and <name>_<component>_header variable should contain the name of a header
+# file associated with it (whatever relative path is normally passed to
+# '#include'). <name>_<component>_header_subdir variable can be used to specify
+# which subdirectory of the include path the headers will be found in.
+# ecm_find_package_components() will then search for the library
+# and include directory (creating appropriate cache variables) and create an
+# imported library target named <name>::<component>.
+#
+# Additional variables can be used to provide additional information:
+#
+# If SKIP_PKG_CONFIG, the <name>_<component>_pkg_config variable is set, and
+# pkg-config is found, the pkg-config module given by
+# <name>_<component>_pkg_config will be searched for and used to help locate the
+# library and header file.  It will also be used to set
+# <name>_<component>_VERSION.
+#
+# Note that if version information is found via pkg-config,
+# <name>_<component>_FIND_VERSION can be set to require a particular version
+# for each component.
+#
+# If SKIP_DEPENDENCY_HANDLING is not set, the INTERFACE_LINK_LIBRARIES property
+# of the imported target for <component> will be set to contain the imported
+# targets for the components listed in <name>_<component>_component_deps.
+# <component>_FOUND will also be set to false if any of the compoments in
+# <name>_<component>_component_deps are not found.  This requires the components
+# in <name>_<component>_component_deps to be listed before <component> in the
+# COMPONENTS argument.
+#
+# The following variables will be set:
+#
+# ``<name>_TARGETS``
+#   the imported targets
+# ``<name>_LIBRARIES``
+#   the found libraries
+# ``<name>_INCLUDE_DIRS``
+#   the combined required include directories for the components
+# ``<name>_DEFINITIONS``
+#   the "other" CFLAGS provided by pkg-config, if any
+# ``<name>_VERSION``
+#   the value of ``<name>_<component>_VERSION`` for the first component that
+#   has this variable set (note that components are searched for in the order
+#   they are passed to the macro), although if it is already set, it will not
+#   be altered
+#
+# Note that these variables are never cleared, so if
+# ecm_find_package_handle_library_components() is called multiple times with
+# different components (typically because of multiple find_package() calls) then
+# ``<name>_TARGETS``, for example, will contain all the targets found in any
+# call (although no duplicates).
+#
+# Since pre-1.0.0.
