This basically creates imported targets from those
pkg-config modules. It also supports static linkage.
The main effort here is that those imported targets
are also exported appropriately. This is implemented
by letting the config script re-run pkg-config as
required.
This target is required so files for header-only libs
show up in Qt Creator. So far it was just a custom target.
However, this way include directories and build flags are
not correctly passed to the code model. So creating an
actual library now.
Previously the case when the dependency of a static library
was provided by a dynamic library has not been handled
correctly leading to linker errors when building the final
application.
* The project directory is part of the include
directives, eg. #include <c++utilities/...
* So the include search path must be one level
above the project directory.
* Add include path of own header files for build
and external use via imported target. Previously
only include dirs required for external libs were
added.
* Using global include dirs is no longer required.
* When PUBLIC_SHARED_INCLUDE_DIRS is empty, adding
"${PUBLIC_SHARED_INCLUDE_DIRS}" to public include dirs
does not leave INTERFACE_INCLUDE_DIRECTORIES property
empty. Instead the source dir is added. So just don't
use quotes here.
* So files generated by moc or qdbusxml2cpp are not
part of coverage statistics
* When filtering files, llvm-cov prints multiple tables
showing coverage on function level.
-> Generate overall coverage stats via awk.
* Append Git revision and ID of latest commit
to version displayed via --help
* Can be turned off via option
* Has no effect if the source dir is not
a Git checkout or Git is not installed
* Implements

- Ensure static versions of 3rd party libs are
found correctly
- Link tests against statically if only static
libraries have been built
- Ensure standard lib is linked statically when
static linkage is enabled
