HPX link error (cmake / MPI)

[eschnett]

I suddenly see this error from HPX:

CMake Error at cmake/HPX_AddExecutable.cmake:116 (add_executable):
  Target "hpx_runtime_exe" links to item " -lmpi_usempi -lmpi_mpifh -lmpi_cxx
  -lmpi" which has leading or trailing whitespace.  This is now an error
  according to policy CMP0004.

I am using cmake 3.0.0.

I have no idea where this comes from but I'll try to investigate.

This looked to me as if it could be caused by recent changes to HPX's build system. If there are no such changes then I'll investigate locally.

Nothing has been changed recently, all new cmake related work is done on a branch (https://github.com/STEllAR-GROUP/hpx/tree/cmake_simplification)

This should be fixed now. Please reopen if the problem still persists.
