# Priority is as same order as follows:
# 1. `Python_LOOKUP_VERSION`: specify major.minor version to find.
# 2. 'Python_FIND_VIRTUALENV': specify 'ONLY' to use virtualenv activated.
# 3. `Python_ROOT`: specify installed location.
# 4. If nothing specified, use default behavior.

# $ cmake -DPython_LOOKUP_VERSION=3.8.0 ..
# $ cmake -DPython_FIND_VIRTUALENV=ONLY ..
# $ cmake -DPython_ROOT=C:\Python38 ..
