# Copy all files from /colmap_installed/ in the builder stage to /usr/local/ in
# the runtime stage. This simulates installing COLMAP in the default location
# (/usr/local/), which simplifies environment variables. It also allows the user
# of this Docker image to use it as a base image for compiling against COLMAP as
# a library. For instance, CMake will be able to find COLMAP easily with the
# command: find_package(COLMAP REQUIRED).
