初学CppUnit，有关cmake

早就听闻CppUnit是个好东西，奈何一直没有仔细研读，现在开始一步步来学习。

网上找了个例子，想先跑跑看看效果，卡在了cmake这一步。

原来cmake v2.8里还没有FindCppUnit这个模块，所幸已经有网友写出了一个可用的版本，先拿来借鉴一下.

#
# Find the CppUnit includes and library
#
# This module defines
# CPPUNIT_INCLUDE_DIR, where to find tiff.h, etc.
# CPPUNIT_LIBRARIES, the libraries to link against to use CppUnit.
# CPPUNIT_FOUND, If false, do not try to use CppUnit.

# also defined, but not for general use are
# CPPUNIT_LIBRARY, where to find the CppUnit library.
# CPPUNIT_DEBUG_LIBRARY, where to find the CppUnit library in debug mode.

FIND_PATH(CPPUNIT_INCLUDE_DIR cppunit/TestCase.h
  /usr/local/include
  /usr/include
)

# With Win32, important to have both
IF(WIN32)
  FIND_LIBRARY(CPPUNIT_LIBRARY cppunit
               ${CPPUNIT_INCLUDE_DIR}/../lib
               /usr/local/lib
               /usr/lib)
  FIND_LIBRARY(CPPUNIT_DEBUG_LIBRARY cppunitd
               ${CPPUNIT_INCLUDE_DIR}/../lib
               /usr/local/lib
               /usr/lib)
ELSE(WIN32)
  # On unix system, debug and release have the same name
  FIND_LIBRARY(CPPUNIT_LIBRARY cppunit
               ${CPPUNIT_INCLUDE_DIR}/../lib
               /usr/local/lib
               /usr/lib)
  FIND_LIBRARY(CPPUNIT_DEBUG_LIBRARY cppunit
               ${CPPUNIT_INCLUDE_DIR}/../lib
               /usr/local/lib
               /usr/lib)
ENDIF(WIN32)

IF(CPPUNIT_INCLUDE_DIR)
  IF(CPPUNIT_LIBRARY)
    SET(CPPUNIT_FOUND "YES")
    SET(CPPUNIT_LIBRARIES ${CPPUNIT_LIBRARY} ${CMAKE_DL_LIBS})
    SET(CPPUNIT_DEBUG_LIBRARIES ${CPPUNIT_DEBUG_LIBRARY}
${CMAKE_DL_LIBS})
  ENDIF(CPPUNIT_LIBRARY)
ENDIF(CPPUNIT_INCLUDE_DIR)

在自己的CMakeLists.txt中加上

set(MY_MODULE_PATH "/home/XXX/usr/share/cmake/Modules") 
#这个是你放FindCppUnit.cmae的路径

LIST(APPEND CMAKE_MODULE_PATH ${MY_MODULE_PATH})

这样就可以使用find_package(CppUnit)了。
