Subject: Warn when doing an out-of-source build and finding in-source build artifacts
X-Git-Tag: OpenSSL_1_1_0-pre6~1073
X-Git-Url: https://git.openssl.org/?p=openssl.git;a=commitdiff_plain;h=ddc606c914e72e770dbe8293a65585b7c3017bba;ds=sidebyside

Warn when doing an out-of-source build and finding in-source build artifacts

The reason to warn is that configuration *may* pick up on
configuration header files that are in the source tree, that might be
for a wildly different configuration than what is expected in the
current out-of-source configuration.
