Description
-------

Make ecm_setup_version interact well with CMP0048

When CMake policy CMP0048 (CMake 3.0) is set to NEW, the project()
command is meant to manage the project's version variables. We therefore
do not set the PROJECT_VERSION variables in this case.

To make sure projects do not have to specify their version in multiple
places, this also allows the keyword "PROJECT" to be passed to
ecm_setup_version instead of an actual version number. In this case, the
version passed to project() will be used.

Testing
-------

Bundled autotests pass. Freshly configured, built and installed KArchive - version header file and KF5ArchiveConfigVersion.cmake correct by inspection. KEmoticons then configured successfully (finding KF5Archive >= 4.96.0).


Thanks,
