From 0c5da90372854bbfb46ea7aacb56add365cee5c7 Mon Sep 17 00:00:00 2001 From: Pete Gadomski Date: Fri, 28 Feb 2014 09:49:38 -0700 Subject: [PATCH] ledger: find Homebrew Python when building --HEAD. When building --HEAD and --with-python, CMake gets confused by multiple python installations, e.g. when both Homebrew and system Pythons exist (see https://github.com/Homebrew/homebrew/issues/10393 for one example). This patch lifts some hacks from https://github.com/Homebrew/homebrew/blob/51d054c/Library/Formula/opencv.rb to point CMake to the Homebrew Python only, if one exists and is installed. N.B. brew test ledger seems to be broken when installed --HEAD for unrelated reasons. Closes #27095.
