Review request for Extra Cmake Modules and Aleix Pol Gonzalez.


Repository: extra-cmake-modules


Description
-------

Not all projects install something to ${CMAKE_INSTALL_PREFIX}/share or ${CMAKE_INSTALL_PREFIX}/lib/qml (e.g. when using qrc files). Currently this results in androiddeployqt (some 5.5 at least) to fail with the deployment file generated by the ECM toolchain file. Because both dirs are hardcoded into the deployment file.

This patch tries to fix that by only adding those dirs which exist in the install folder.

Just setting the field android-extra-plugins to an empty string resulted
in androiddeployqt complaining about
    "External resource  does not exist or not a correct directory!"
so the field is completely left out now if no plugin data dirs are found.
So I instead propose to insert the complete field only if there is content.
For consistency the same is done with the android-extra-libs field.
