Torsten Rasmussen 0a64b08062 cmake: set Zephyr_DIR when loading Zephyr package ... CMake find_package() is expected to set the cached variable Zephyr_DIR with the value of the package included. Zephyr_DIR in the CMakeCache is used by CMake re-runs for `find_package(Zephyr)` to directly lookup the package to use. The Zephyr_DIR is set correctly when a single Zephyr workspace is used but may in some other cases be set to `Zephyr_DIR=Zephyr_DIR-NOTFOUND`. This causes CMake to rerun the Zephyr package search mechanism and loop through potential candidates before loading the correct Zephyr installation. After a second run, Zephyr_DIR is n some cases set to `Zephyr_DIR=<path-to-including-Zephyr>` which might be different from the Zephyr in use. The Zephyr_DIR should be pointing to the package defined by ZEPHYR_BASE. This commit ensures that when ZephyrConfig.cmake package is loaded, then Zephyr_DIR is set correctly.
