Re: [CMake] CMake 2.8.1 / Win: Neither if nor else?`
Hi Torsten Torsten Rohlfing ha scritto: IF(ZLIB_FOUND) MESSAGE( WARNING HAVE system zlib ) ELSEIF(ZLIB_FOUND) MESSAGE( WARNING NO system zlib ) ENDIF(ZLIB_FOUND) [...] Can someone explain to me what I am missing? You are not missing anything, simply you are wrongly using the IF construct because the second command should be ELSE, not ELSEIF. Your construct can be interpreted like this one IF(ZLIB_FOUND) MESSAGE( WARNING HAVE system zlib ) ELSE(ZLIB_FOUND) IF(ZLIB_FOUND) MESSAGE( WARNING NO system zlib ) ENDIF(ZLIB_FOUND) ENDIF(ZLIB_FOUND) so, of course you get no output if zlib is not found, and two outputs if zlib is found. The right construct is IF(ZLIB_FOUND) MESSAGE( WARNING HAVE system zlib ) ELSE(ZLIB_FOUND) MESSAGE( WARNING NO system zlib ) ENDIF(ZLIB_FOUND) Bye Droscy ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

The WARNING option to message() is new to CMake 2.8. For better compatibility with CMake 2.6 and lower, simply omit it which should give you a similar effect. -- Philip Lowman ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
