# establish default value for XO_SYMLINK_INSTALL.
#
# may want to use this for a nested build,
# where we want to run cmake for nested codebase using externalproject_add().
#
# in this case:
# 1. will need to build+install nested project foo to temporary location in build tree,
# so that build artifacts (such as fooConfig.cmake) are available to depending
# projects
# 2. bona fide install with (for example) copied .hpp files interferes with
# cross-codebase development.
# 2a. want changes to original .hpp files to trigger rebuild of depending codebases.
# This won't happen if depending project relies on a copy
# 2b. want IDE that observes compiler commands (i.e. LSP) to visit .hpp files
# in their original codebase, since that's the correct place to make any edits.
