[CMake] Python: site-packages vs. dist-packages

[Nico Schlömer]

Hi all,

I have a CMake build for a Python package where the installation directory is

SET(PyTrilinos_INSTALL_DIR
  ${PyTrilinos_INSTALL_PREFIX}/lib/python${PYTHON_VERSION}/site-packages/MyPackage
  CACHE PATH "The path where MyPackage will be installed"
  )

This creates a problem for a default Ubuntu install which requires
system packages to be installed into dist-packages.
Is there a variable that I could provide instead of
${PyTrilinos_INSTALL_PREFIX}/lib/python${PYTHON_VERSION}/site-packages/,
something like ${DEFAULT_PYTHON_INSTALL_DIR}? How do you handle this?
