cmake configuration with OpenBLAS fails

[edoapra]

I am trying to configure GA to use OpenBLAS on Ubuntu linux with the current develop branch

cmake   -DLINALG_VENDOR=OpenBLAS -DLINALG_PREFIX=/usr/lib/x86_64-linux-gnu/ -DENABLE_BLAS=ON -DLINALG_REQUIRED_COMPONENTS=lp64 ..

returns

CMake Error at /home/edo/sandb/ga-develop/b1/_deps/lapackpp-build/CMakeFiles/CMakeTmp/CMakeLists.txt:20 (add_executable):
  Target "cmTC_69c6c" links to target "OpenMP::OpenMP_CXX" but the target was
  not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?
