Subject: tools: cmake: fix compatibility with LibreSSL as well
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0b3b8c83c047137ed83f5697ed44c04dbed5bbeb;p=openwrt%2Fstaging%2Fyousong.git

tools: cmake: fix compatibility with LibreSSL as well

Sadly, LibreSSL claims to be OpenSSL v2.0.0 while not providing the new
interfaces introduced with OpenSSL v1.1.x, so extend the pre-OpenSSL 1.1.x
compat checks to consider LibreSSL as well.
