Marc Herbert debade9121 tests: make find_package(Zephyr...) REQUIRED ... because it is (required). This makes a difference when building with CMake and forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package registry. In this particular case, REQUIRED turns this harmless looking log statement: -- Could NOT find Zephyr (missing: Zephyr_DIR) -- The C compiler identification is GNU 9.3.0 -- The CXX compiler identification is GNU 9.3.0 -- Check for working C compiler: /usr/bin/cc -- ... -- ... -- ... -- Detecting CXX compile features -- Detecting CXX compile features - done CMake Error at CMakeLists.txt:8 (target_sources): Cannot specify sources for target "app" which is not built by this project. ... into this louder, clearer, faster and (last but not least) final error: CMake Error at CMakeLists.txt:5 (find_package): Could not find a package configuration file provided by "Zephyr" with any of the following names: ZephyrConfig.cmake zephyr-config.cmake Add the installation prefix of "Zephyr" to CMAKE_PREFIX_PATH or set "Zephyr_DIR" to a directory containing one of the above files. If "Zephyr" provides a separate development package or SDK, be sure it has been installed. -- Configuring incomplete, errors occurred!

Title: Memory Slab APIs

Description:

This test verifies that the kernel memory slab APIs operate as expected.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------

===================================================================
