Unknown Cmake command "target_add_definitions"

There's an error when trying to compile with ZMQ using static library

$ cmake -DENABLE_PACKAGE_BUILD=ON -DCPACK_BINARY_BUNDLE=ON -DSTATIC_STANDARD_LIB=ON -DZMQ_USE_STATIC_LIBRARY=ON -DUSE_BOOST_STATIC_LIBS=ON -DCMAKE_INSTALL_PREFIX="/Users/$USER/local/helics-develop/" ../

I have the following version of cmake

$ cmake --version
cmake version 3.11.4

CMake suite maintained and supported by Kitware (kitware.com/cmake).

There appears to be an issue with this line.

@phlptp I tried the change that you suggested but this still causes an error in the cmake configuration step
