Subject: Find the include directory for libunwind.h.
X-Git-Url: https://git.cworth.org/git?p=vogl;a=commitdiff_plain;h=23c18e4ca34e89d0032c38f7ed32c0a39c185d36

Find the include directory for libunwind.h.

This allows finding libunwind that has been installed in a non-standard location
just by setting CMAKE_PREFIX_PATH.
