From 2d3594b1bbd48d0dc7a071a6806c75c89341e1c5 Mon Sep 17 00:00:00 2001 From: "Marcus D. Hanwell" Date: Mon, 10 Jan 2011 13:44:45 -0500 Subject: Python additional version support, bug #10279. Introduced an additional variable, Python_ADDITIONAL_VERSIONS, to both FindPythonLibs and FindPythonInterp. Changed FindPythonInterp to loop over versions rather than hardcoding all versions (more like libs). --- Modules/FindPythonInterp.cmake | 46 +++++++++++++++++++++++++----------------- Modules/FindPythonLibs.cmake | 34 ++++++++++++++++++------------- 2 files changed, 47 insertions(+), 33 deletions(-) diff --git a/Modules/FindPythonInterp.cmake b/Modules/FindPythonInterp.cmake index 645ca79..f2c116f 100644 --- a/Modules/FindPythonInterp.cmake +++ b/Modules/FindPythonInterp.cmake @@ -2,8 +2,9 @@ # This module finds if Python interpreter is installed and determines where the # executables are.
