Subject: tools: cmake: use pkg-config to discover libcrypto linker flags
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f9b253147a27d4fbe2558624fc68323ff9de2f22;p=openwrt%2Fstaging%2Fblocktrron.git

tools: cmake: use pkg-config to discover libcrypto linker flags

LibreSSL's libcrypto.so has an indirect dependency to librt for clock_gettime()
on Linux.

Use pkg-config to portably discover the required linker flags.
