Use-case is explained in the documentation. This implementation
takes care that the additional libs actually occur at the end
of the linker line despite the use of imported targets with
INTERFACE_LINK_LIBRARIES. It might still not be perfect but
sufficient for current use-cases.
* Prevent imported library paths pointing to build directory
ending up in pkg-config file
* Handle targets which reference other targets but have not pkg-config
module
* Fix check for BUNDLED_TARGETS
Even if QMake tells us that would be the right location because
it breaks development setups which use a custom install prefix
and set QT_PLUGIN_PATH accordingly.
* Allow exporting targets from 3rd party projects which are
built within my own projects. This is required if the build
scripts of these 3rd party projects don't have an export on
their own but are used in the public interface or as a dependency
of a static library.
* Add those libraries to the pkg-config file as well.
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.
