# - Check if a symbol exists as a function, variable, or macro in C++ # CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>) # # Check that the <symbol> is available after including given header # <files> and store the result in a <variable>. Specify the list # of files in one argument as a semicolon-separated list. # CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as opposed # to CHECK_SYMBOL_EXISTS(), which works only for C. # # If the header files define the symbol as a macro it is considered # available and assumed to work. If the header files declare the # symbol as a function or variable then the symbol must also be # available for linking. If the symbol is a type or enum value # it will not be recognized (consider using CheckTypeSize or # CheckCSourceCompiles). # # The following variables may be set before calling this macro to # modify the way the check is run: # # CMAKE_REQUIRED_FLAGS = string of compile command line flags # CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) # CMAKE_REQUIRED_INCLUDES = list of include directories # CMAKE_REQUIRED_LIBRARIES = list of libraries to link #============================================================================= # Copyright 2003-2011 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) include(CheckSymbolExists) macro(CHECK_CXX_SYMBOL_EXISTS SYMBOL FILES VARIABLE) _CHECK_SYMBOL_EXISTS("${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/CheckSymbolExists.cxx" "${SYMBOL}" "${FILES}" "${VARIABLE}" ) endmacro()
