This is the contemporary way of including find modules and including the
find module this way avoids cmake errors in conjunction with
find_package_handle_standard_args().

When building packages, especially when source packages are used, git is
not necessarily available or the source isn't provided in git. In those
cases it wasn't possible to set the GIT_REVISION and --version shows
"n/a" for the git revision.
If the file .source_version is available now the content of it is used
as GIT_REVISION. Packagers might want to add a .source_version file
when they don't build the packages from git.
Possible breaking change:
The variable PRODUCT_VERSION isn't available anymore. Use GIT_REVISION
instead.
Although exported rdtk isn't really mature and stable yet therefore it is
not exported/installed anymore. In case FreeRDP is built without
static libraries librdtk is installed as part or the
FreeRDP-ShadowTargets exports as this is the only place it is used right
now.
rdtk was initially 1.0.0 then changed to 0.0.1.
To have a clean cut and prevent problems on systems which already have
FreeRDP in a version where rdtk was 1.0.0 increase it to 2.0.0
With this commit the "exported" components (usable with pkg-config and
cmake find module package)
* winpr - winpr library and headers
* freerdp - core library and headers
* freerdp-client - client specific library
* freerdp-server - server specific library
* rdtk - rdtk headers and library
To allow the installation of multiple different version (different major
number) the include files were moved into the respective sub folder:
freerdp -> freerdp{MAJOR}/freerdp (currently freerdp2/freerdp/)
winpr -> winpr{MAJOR}/winpr (currently winrp1/winpr/)
rdtk -> rdpk{MAJOR}/rdtk (currently rdtk0/rdtk/
The generated pkg-config and cmake find modules now also include the major
version number. Currently the following pkg-config are generated and
installed.
* winpr1
* freerdp2
* freerdp-server2
* freerdp-client2
* rdtk0
As cmake is able to handle multiple versions out of the box the
following can be used to find a specific module:
find_package(WinPR)
find_package(FreeRDP)
find_package(FreeRDP-Server)
find_package(FreeRDP-Client)
find_package(RdTk)
As cmake doesn't automatically resolve dependencies for packages it is
necessary to manually include the requirements. For example if
FreeRDP-Client is required WinPR and FreeRDP need to be included
(find_package) as well.
This commit also fixes the installation when STATIC_CHANNELS are built.
WITH STATIC_CHANNELS all channels are linked into libfreerdp-client, for
this all channels are generated as linker archive and linked together in
the final step. Before the intermediate linker archives were, although
not required and useful, installed. Same applies for server side
channels.
