Subject: [PATCH 2/5] tools lib perf: Add dependency test to install_headers
Date: Thu, 1 Dec 2022 20:57:40 -0800 [thread overview]
Message-ID: <20221202045743.2639466-3-irogers@google.com> (raw)
In-Reply-To: <20221202045743.2639466-1-irogers@google.com>
Compute the headers to be installed from their source headers and make
each have its own build target to install it. Using dependencies
avoids headers being reinstalled and getting a new timestamp which
then causes files that depend on the header to be rebuilt.
