Subject: Force /usr/local/include as search path on FreeBSD
X-Git-Tag: accepted/tizen/base/20180629.140029~6937^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c6e325899bcdc2bb3f0feb1179f1ad3bef10d91;p=platform%2Fupstream%2Fcoreclr.git

Force /usr/local/include as search path on FreeBSD

CMake does not find headers installed in /usr/local/include by default. On
FreeBSD this is the default location for libunwind.h though. Define
CMAKE_REQUIERED_INCLUDE to include both /usr/local/include and /usr/include.
This change only affects FreeBSD. Also FreeBSD (like Darwin) does not work with
_DEFAULT_SOURCE or _POSIX_C_SOURCE defined. Closes #547
