>Description:
trying to build opencv-core in a poudriere bulk with clang as the default compiler. I'm getting an error at configure :

CMake Error at /usr/local/share/cmake/Modules/CMakeTestCXXCompiler.cmake:54 (message):
  The C++ compiler "/usr/bin/clang++" is not able to compile a simple test
  program.

  It fails with the following output:

>How-To-Repeat:
create a 9.2-RELEASE amd64 poudriere jail with a name (let's call a variable ${jail name}
edit a /usr/local/etc/poudriere.d/${jail name}-make.conf
and save this in it :

CC=clang
CXX=clang++
CPP=clang-cpp
WERROR=
NO_WERROR=

and try to bulk graphics/opencv-core
