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.
