Revision 6650b0fa43ef55e8bad9188c584f40d515f38bd6 authored by Brad King on 25 June 2014, 17:34:15 UTC, committed by Brad King on 25 June 2014, 17:37:46 UTC
Since commit v3.0.0-rc1~374^2 (Refactor internal resource location APIs and initialization, 2013-11-07) a bootstrap-built "cmake" tries to reference "ctest" and "cpack" executables next to itself, which never exist. Teach cmSystemTools::FindCMakeResources, when bootstrap-built, to refer to the "ctest" and "cpack" executables in the location where they will be built after "make".

# FindBacktrace
# -------------
#
# Find provider for backtrace(3).
#
# Checks if OS supports backtrace(3) via either libc or custom library.
# This module defines the following variables::
#
# Backtrace_HEADER - The header file needed for backtrace(3). Cached.
# Could be forcibly set by user.
# Backtrace_INCLUDE_DIRS - The include directories needed to use backtrace(3) header.
# Backtrace_LIBRARIES - The libraries (linker flags) needed to use backtrace(3), if any.
# Backtrace_FOUND - Is set if and only if backtrace(3) support detected.
#
# The following cache variables are also available to set or use::
#
# Backtrace_LIBRARY - The external library providing backtrace, if any.
# Backtrace_INCLUDE_DIR - The directory holding the backtrace(3) header.
#
# Typical usage is to generate of header file using configure_file() with the
# contents like the following::
#
# #cmakedefine01 Backtrace_FOUND
# #if Backtrace_FOUND
# # include <${Backtrace_HEADER}>
# #endif
#
# And then reference that generated header file in actual source.
