# ========================================================================
# Usage:
#   cd $WK; cd ecbuild/release/; sh -x ../../cmake.sh release; make ; make install
#   calling 'sh -x ../../cmake.sh release' will generate setup.py from setup.py.in
# Issues:
#   Cannot test cmake install, since it will always install to 
#     /usr/local/apps/python/current/lib/python2.7/site-packages/ecflow
#
# To test install manually, we can:
#   python3 setup.py --help-commands # help
#
#   cd $WK/libs/pyext
#   rm -rf build/                     # for a clean build
#   python setup.py build_ext         # build C/C++ extensions (compile/link to build directory)
#   python setup.py install --home=~
