The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=15687 ====================================================================== Reported By: Adn Assigned To: ====================================================================== Project: CMake Issue ID: 15687 Category: CMake Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2015-08-07 04:07 EDT Last Modified: 2015-08-07 04:07 EDT ====================================================================== Summary: target_include_directories(): SYSTEM option does not seem to work when targeting Xcode. Description: Following the documentation for target_include_directories(): http://www.cmake.org/cmake/help/v3.0/command/target_include_directories.html
We tried to provide the SYSTEM argument to target_include_directories(), to prevent a third party library to issue a lot of warnings. We expected it to put the library's include path on the C++ flags line, behind "-isystem", but it had actually no effect, still using this path as if SYSTEM was not given. We attached in "Steps To Reproduce" the minimal example reproducing this problem in our environment: *CMake v3.3.0 (also tested with v3.0.0 for the same results) *OS X 10.9.5 *Xcode 5.1.1 There is a mailing list thread discussion this issue, that seems to point to the incriminated code: http://www.cmake.org/pipermail/cmake/2015-August/061322.html Steps to Reproduce: cmake_minimum_required(VERSION 3.0) find_package(Boost 1.49 COMPONENTS) project(system_dependencies) add_executable(${PROJECT_NAME} main.cpp) target_include_directories(${PROJECT_NAME} SYSTEM PUBLIC ${Boost_INCLUDE_DIRS}) Additional Information: There is also a Stack Overflow question: http://stackoverflow.com/q/31722426 ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-08-07 04:07 Adn New Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
