Another test build with just BUILD_TESTING to OFF -> problem appears.Ĭonclusion so far: Setting BUILD_TESTING to OFF is causing this issue, in conjunction with using Make/Ninja generator, and the CTEST_USE_LAUNCHERS option set through HDF5’s CTestScript.cmake. After that, another completely fresh test build without changing any settings in HDF5options.cmake -> problem did not occur. Just for testing, I now did a fresh manual build, with just the BUILD_SHARED_LIBS and BUILD_TESTING set to OFF - same issue. My automated build with which I have these problems follows these steps already (with changes and additions to HDF5config.cmake, as noted above, to speed up build times). It can be used to support multiple native build environments including make in Linux/Unix, Apple’s Xcode, and Microsoft Visual Studio. CMake is a cross-platform open-source meta-build system that can build, test, and package software. The link above also shows how to select a specific compiler for C/C++. You can override this with various settings: For example: setsourcefilesproperties (yourfile.c LANGUAGE CXX) Would compile. #if(NOT "$ -DCTEST_USE_LAUNCHERS:BOOL=ON")Ĭan you start with a clean location and follow the steps in the INSTALL_CMake.txt file and just go with the defaults? In this article, we’ll learn to install cmake on Linux. cmake uses the extension to choose the compiler, so just name your files. CMake is cross platform) which you can then make using the generated makefiles. Because the build runs fine if I just change CTestScript.cmake (line 53) to: # Launchers work only with Makefile and Ninja generators. cmake is a system to generate make files based on the platform (i.e. If CTEST_USE_LAUNCHERS itself is harmless, then there must be some other non-harmless setting tightly coupled to it. and cmake 3.24.1ĬTEST_USE_LAUNCHERS error only happens when the build cannot find the source (at least for me).ĬTEST_USE_LAUNCHERS setting is really harmless. CMake is invoked with a specific set of switches that are defined as part of a default CMake configuration that VS creates under the name x86-Debug if this configuration is insufficient for CMake to successfully create its cache, you can further configure it: how to configure CMake is explained later in the post. Of course, contacting the developer, suggesting that they deal with the policy in source, is a good practice.If it helps something, this is on Ubuntu 20.04, with g++ 9.40. In such a case, you can use -DCMAKE_POLICY_DEFAULT_CMP to get the behavior you need, without editing CMakeLists.txt. Without setting a policy, CMake will ignore the -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON. One reason might be to enable the link-time optimization (also called interprocedural optimization). However, sometimes as a user of a software, you have a good reason to set a policy when you are installing the project. INTERPROCEDURAL_OPTIMIZATION property will be ignored for target Use theĬmake_policy command to set the policy and suppress this warning. Run "cmake -help-policy CMP0069" for policy details. Policy CMP0069 is not set: INTERPROCEDURAL_OPTIMIZATION is enforced whenĮnabled. CMake Warning (dev) at c/tools/CMakeLists.txt:22 (add_executable): The messages are there for the project developers. The CMake policy warnings at the end explicitly inform users that they should not concern themselves with the messages.
