FindCppUnit
-----------
Find CppUnit include dirs and libraries
Use this module by invoking find_package with the form::
find_package(CppUnit
[version] [EXACT] # Minimum or EXACT version
[REQUIRED] # Fail with error if CppUnit is not found
)
IMPORTED Targets
^^^^^^^^^^^^^^^^
``CppUnit::cppunit``
This module defines IMPORTED target CppUnit::cppunit, if CppUnit has been
found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``CppUnit_FOUND``
True if the system has the CppUnit library.
``CppUnit_VERSION``
The version of the CppUnit library which was found.
``CppUnit_INCLUDE_DIRS``
Include directories needed to use CppUnit.
``CppUnit_RELEASE_LIBRARIES``
Libraries needed to link to the release version of CppUnit.
``CppUnit_RELEASE_LIBRARY_DIRS``
CppUnit release library directories.
``CppUnit_DEBUG_LIBRARIES``
Libraries needed to link to the debug version of CppUnit.
``CppUnit_DEBUG_LIBRARY_DIRS``
CppUnit debug library directories.
Deprecated - use [RELEASE|DEBUG] variants:
``CppUnit_LIBRARIES``
Libraries needed to link to CppUnit.
``CppUnit_LIBRARY_DIRS``
CppUnit library directories.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``CppUnit_INCLUDE_DIR``
The directory containing ``cppunit/Portability.h``.
``CppUnit_LIBRARY``
The path to the CppUnit library.
Hints
^^^^^
Instead of explicitly setting the cache variables, the following variables
may be provided to tell this module where to look.
``CppUnit_ROOT``
Preferred installation prefix.
``CPPUNIT_INCLUDEDIR``
Preferred include directory e.g. <prefix>/include
``CPPUNIT_LIBRARYDIR``
Preferred library directory e.g. <prefix>/lib
``CPPUNIT_DEBUG_SUFFIX``
Suffix of the debug version of CppUnit libs. Defaults to "_d".
``SYSTEM_LIBRARY_PATHS``
Global list of library paths intended to be searched by and find_xxx call
``CPPUNIT_USE_STATIC_LIBS``
Only search for static cppunit libraries
``DISABLE_CMAKE_SEARCH_PATHS``
Disable CMakes default search paths for find_xxx calls in this module
