# mimic running "ctest", i.e. the "test" section of CMakeLists.txt
#   - does not redirect stdout
#   - allows freely setting $upx_exe_runner, while CMake is restricted to configure-time settings
#
# requires:
#   $upx_exe                (required, but with convenience fallback "./upx")
# optional settings:
#   $upx_exe_runner         (e.g. "qemu-x86_64 -cpu Nehalem" or "valgrind")
