# - Find Python
|
|
# This module finds if Python is installed and determines where the include files
|
|
# and libraries are. It also determines what the name of the library is. This
|
|
# code sets the following variables:
|
|
#
|
|
# PYTHON_EXECUTABLE = full path to the python binary
|
|
# PYTHON_INCLUDE_PATH = path to where python.h can be found
|
|
# PYTHON_LIBRARY = path to where libpython.so* can be found
|
|
# PYTHON_LFLAGS = python compiler options for linking
|
|
