| # -------- |
| # |
| # Find the native realtime includes and library. |
| # |
| # IMPORTED Targets |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module defines :prop_tgt:`IMPORTED` target ``LIBM::LIBM``, if |
| # LIBM has been found. |
| # |
| # Result Variables |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module defines the following variables: |
| # |
| # :: |
| # |
| # LIBM_INCLUDE_DIRS - where to find math.h, etc. |
| # LIBM_LIBRARIES - List of libraries when using libm. |
| # LIBM_FOUND - True if math library found. |
| # |
| # Hints |
| # ^^^^^ |
| # |
| # A user may set ``LIBM_ROOT`` to a math library installation root to tell this |
| # module where to look. |
