| # FindAPR |
| # -------- |
| # |
| # Find the native Apache Portable Runtime includes and library. |
| # |
| # IMPORTED Targets |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module defines :prop_tgt:`IMPORTED` target ``APR::APR``, if |
| # APR has been found. On Windows, it may define the :prop_tgt:`IMPORTED` |
| # target ``APR::APR_static`` if the static libraries are found. |
| # |
| # Result Variables |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module defines the following variables: |
| # |
| # :: |
| # |
| # APR_FOUND - True if APR was found. |
| # APR_VERSION - The version of APR found (x.y.z) |
| # APR_CONTAINS_APRUTIL - True if the APR major version is 2 or greater. |
| # APR_INCLUDES - Where to find apr.h, etc. |
| # APR_LIBRARIES - Linker switches to use with ld to link against APR |
| # |
| # :: |
| # |
| # APR_EXTRALIBS - Additional libraries to link against |
| # APR_CFLAGS - The flags to use to compile. |
| # APR_STATIC_LIBS - On Windows: list of APR static libraries |
| # APR_RUNTIME_LIBS - On Windows: list of APR runtime DLLs |
| # |
| # Hints |
| # ^^^^^ |
| # |
| # A user may set ``APR_ROOT`` to an APR installation root to tell this |
| # module where to look. This variable must be defined on Windows. |
