[Openamp-rp] [OpenAMP/libmetal] 04cf5d: cmake: fix VERSION file path

Branch: refs/heads/master Home: https://github.com/OpenAMP/libmetal Commit: 04cf5d9e0ef562d676cd3f58530fed4e1901f428 https://github.com/OpenAMP/libmetal/commit/04cf5d9e0ef562d676cd3f58530fed4e1... Author: Arnaud Pouliquen arnaud.pouliquen@foss.st.com Date: 2021-05-04 (Tue, 04 May 2021)

Changed paths: M CMakeLists.txt M cmake/options.cmake

Log Message: ----------- cmake: fix VERSION file path

cmake fails when the variable CMAKE_SOURCE_DIR does not point to the libmetal directory. This is the case, for example, for the Zephyr project.

Fix by defining LIBMETAL_ROOT_DIR in the main CmakeLists.txt.
