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.
