# Shared core for tensilelite-client and cpu-gemm-driver.
#
# Both executables consume nearly the same sources, link line, include
# directories, compile definitions, C++ standard, and sanitizer flags. Owning
# them on a single STATIC helper target removes a `foreach(target ...)` loop
# that applied identical properties to two targets, a `COMMON_CLIENT_SOURCES`
# variable that hid the source list from `target_sources` (and from IDE
# navigation), and three duplicated `target_include_directories` calls.
#
# Each executable is now a thin wrapper that adds only its `main` translation
# unit and links to this helper.
