# Add a python test from a python file
# One cannot simply do:
# SET(ENV{PYTHONPATH} ${LIBRARY_OUTPUT_PATH})
# SET(my_test "from test_mymodule import *\;test_mymodule()")
# ADD_TEST(PYTHON-TEST-MYMODULE  python -c ${my_test})
# Since cmake is only transmitting the ADD_TEST line to ctest thus you are loosing
# the env var. The only way to store the env var is to physically write in the cmake script
# whatever PYTHONPATH you want and then add the test as 'cmake -P python_test.cmake'
#
# Usage:
# SET_SOURCE_FILES_PROPERTIES(test.py PROPERTIES PYTHONPATH
#   "${LIBRARY_OUTPUT_PATH}:${VTK_DIR}")
# ADD_PYTHON_TEST(PYTHON-TEST test.py)
