# modifications:
|

|
|
# - remove linkage against gcc_eh because it was causing segfaults in various of our unit tests
|
||
|
|
|

|
|
# - Try to find libunwind
|
||
|
|
# Once done this will define

# LIBUNWIND_FOUND - system has libunwind
|

|
|
# LIBUNWIND_INCLUDE_DIR - the libunwind include directory
|

# LIBUNWIND_LIBRARIES - Link these to use libunwind
