From cbcc680c7707a0ed2ae8fa673c15789c610c988d Mon Sep 17 00:00:00 2001 From: Mark Stemm Date: Wed, 16 Feb 2022 17:32:54 -0800 Subject: [PATCH] Cmake function to copy files from source to build dir, as a target Define a cmake function copy_files_to_build_dir(source_files, targetsuffix) that defines a single custom target and single custom command to copy the set of source files to CMAKE_CURRENT_BINARY_DIR. All of the real work is done via cmake -E copy_if_different. This function will replace the nearly identical cmake code in several other directories. This function has the advantage of being a single target for the set of source files instead of a target per-file.
