After investigating further, it appears that it's a compiler issue.

The example were compiled with the default Clang compiler.

My application though has to compile with GCC 7 built from source, since
OpenMP which I need is not supported by Clang.

As you will notice hereunder, GCC was retrieved through homebrew via

*brew install gcc --without-multilib
*
I switch compilers by adding the following two lines before project() in my
CMakeLists.txt:
*
set(CMAKE_C_COMPILER /usr/local/Cellar/gcc/7.1.0/bin/gcc-7 CACHE STRING "C
Compiler" FORCE)
set(CMAKE_CXX_COMPILER /usr/local/Cellar/gcc/7.1.0/bin/g++-7 CACHE STRING
"C++ Compiler" FORCE)
*
If I do so in the Poisson_surface_reconstruction_example, then I am getting
the same undefined symbol errors. However removing them and letting the
system use Clang allows the build to proceed.


Any thoughts?
