# If you are like me, and didn't know how DSTROOT and INSTALL_PATH options work, then here's what Xcode help says
# about them:
#
# DSTROOT:
#  "The path at which all products will be rooted when performing an install build. For instance, to install
#   your products on the system proper, set this path to `/`. Defaults to `/tmp/$(PROJECT_NAME).dst` to prevent
#   a *test* install build from accidentally overwriting valid and needed data in the ultimate install path.
#   Typically this path is not set per target, but is provided as an option on the command line when performing an
#   `xcodebuild install`. It may also be set in a build configuration in special circumstances."
#
# INSTALL_PATH:
#  "The directory in which to install the build products. This path is prepended by the DSTROOT."
#
# Starting with Sonoma, xcodebuild install (without clean) stopped replacing existing binary in the DSTROOT.
