Subject: CMake: don't complain about missing nroff
X-Git-Tag: curl-7_72_0~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ac3a5df0e0726120998218969192750326bbd20;p=thirdparty%2Fcurl.git

CMake: don't complain about missing nroff

The curl_nroff_check() was always being called, and complaining if
*NROFF wasn't found, even when not making the manual.

Only check for nroff (and complain) if actually making the manual

Closes #5817
