# Adopting submodule builds directly into this cmake.
# Submodule builds will pickup dependent xo artifacts directly
# from sibling build dirs.
# (Contrast with a build that relies on install step).
# In particular,  configure step in satellite projects
# needs to avoid using cmake find_package() on sibling xo projects:
# 1. .cmake support files
#      fooConfig.cmake
#      fooConfigVersion.cmake
#      fooTargets.cmake
#    won't have been installed
# 2. In any case,  they point to final install location;
#    we need build location
