I'm aware

Build all targets, in this particular case, the tests.

Well, I see that I have not mentioned everything.
The generated array/CMakeLists.txt includes this

if(BUILD_TESTING AND EXISTS "${CMAKE_CURRENT_SOURCE_DIR}/test/CMakeLists.txt")
  add_subdirectory(test)
endif()

and I added array/test/CMakeLists.txt based on
https://github.com/boostorg/assert/blob/develop/test/CMakeLists.txt
which seems Boost.CMake common if not canonical.
