svn commit: r1844404 - /serf/trunk/build/FindAPR.cmake

[br...@apache.org]

Author: brane

New Revision: 1844404

URL: http://svn.apache.org/viewvc?rev=1844404&view=rev
Log:
Fix a bug in the CMake build that caused APR and APR-Util libraries to
become "not found" after they had already been found in a non-default
library path, when Serf is built as part of a larger project.

* build/FindAPR.cmake (_apru_location): Unset the _dir, _lib and _extra
   local variables so that they don't inherit unhelpful strange values
   from any parent CMake environments.
