FindBacktrace — CMake 3.10.2 Documentation

# 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.
