project-template: use lib install dir defined by GNUInstallDirs (#26)

* project-template: use lib install dir defined by GNUInstallDirs

this should fix library search problems on Tumbleweed
project-template installs cmake-config files to library destination
note, individual projects also need to be changed, for installation of actual libs

Use imported target for ApplicationCore but keep Adapter_LINK_FLAGS which should be filled with link
flags from Adapters that do not yet support cmake-exports

and migrate it to use CDD syntax

* use imported targets where possible

also for the export

* cmake: remove explicit definitions for downstream projects

* increase minor version

will be done for all projects using cmake-exports

* remove --export-dynamic linker flag

because it makes no sense for libs

Wip/11221 modernize cmake (#25)

This provides ChimeraTK::<project-name> as cmake imported target.
Variables <project_name>_INCLUDE_DIRS, <project_name>LIBRARY_DIRS, <project_name>_LIBRARIES, <project_name>_CXX_FLAGS, <project_name>_LINKER_FLAGS are provided for compatibility but are generated from cmake-exports where possible and cmake imported targets should be preferred.

* provide function for option array conversion
to be used with target_compile_options etc + FindPackage results, where
findPackage results are of incorrect/old format

* FindDOOCS:
 - DOOCS components as imported targets
 - clean up no longer needed tweaks
 - add timinglib as component
 - make use of log levels and respect QUIET argument

* add_dependency: fail on wrong add_dependency usage
this was unseen since it worked in most cases but in general does not
in particular was causing trouble with imports from cppext
second arg must be version number

* pkgconfig exports
 - generated from cmake-exports
 - make linker flags come before libs, order is required e.g. for --no-as-needed flag
 - remove duplicates in output

* FindGccAtomic
- do not put absolute lib path in output since it was causing trouble with yocto builds. Should be in system lib
paths anyway. Also, make GccAtomic variable output name more consistent.

update project template

This allows easier debugging as all lines can be reached. The tsan build uses
"-o1" for performance reasons.
For asan and Debug build we use "-o0", which includes this flag, and for the
release builds we want as much optimisation we can get.

* Update license files in example projects

* Fix deprecation warning in template project

update project template

The upcoming version of the config generator script package will need
more files to be copied into the build directory. This change simply
copies all files and does not rely on a particular structure.

This is the implementation for the specification change done in a recent
commit.
