They may be set by the project, a toolchain file or other third-party packages. These variables can influence CMake commands provided by Qt. This means that only selected symbols are exported. On Unix, a boolean that describes whether Qt libraries and plugins were compiled with -fvisibility=hidden. Instead, you need to use the targets starting with Qt6. Hides the imported targets starting with Qt. It stores the top-level project name that you set with project command. In CMake projects there is a variable called CMAKEPROJECTNAME. So let’s gradually create a CMakeLists.txt for the library project. Hides commands that start with qt_, leaving only the versioned ones starting with qt6_. Everything from this list is handled by CMake. If not set, the first find_package call defines the default version.Ī string that holds the infix used in library names, when Qt is configured with -libinfix. If set to 6, they will call their counterpart starting with qt6_. If set to 5, commands starting with qt_ will call their counterpart starting with qt5_. Use this instead: (create an empty list if CMAKEFINDROOTPATH does not exist) if(NOT. It needs to be set to either 5 or 6 before the respective find_package() calls. Configure projects Project formats CMake CMake build system CMakeLists.txt CMakeLists.txt Last modified: 11 January 2023 CMakeLists.txt file contains a set of directives and instructions describing the project's source files and targets (executable, library, or both). Do not quote variables that CMake expects to be a list. Let’s create a new CMake project in CLion. When you create a new CMake project in CLion, a CMakeLists.txt file is automatically generated under the project root. Installation variablesĪdditionally, there are also variables that don't relate to a particular package, but to the Qt installation itself.Īn integer that controls the Qt version that qt_ commands forward to in case of mixed Qt 5 and Qt 6 projects. Simple CMake project CMake is a meta build system that uses scripts called CMakeLists to generate build files for a specific environment (for example, makefiles on Unix machines). Any CMake target of type OBJECT or INTERFACE will ignore the feature aspect of the expression and instead be linked in the standard way. The following limitations should also be noted: The library-list can specify CMake targets or libraries. Then, use graphviz to create a dot file, as in this answer: cmake -graphvizgraph.dot. First, in your source directory ('project'): mkdir build & cd build cmake. The name of the imported target for the module: Qt5::WidgetsĪ list of private include directories to use when building against the library and using private Qt API.Ī string containing the module's version.įor all packages found with find_package, equivalents of these variables are available they are case-sensitive. This creates a circular dependency between groups: lib1A-> lib2B-> lib1A. I realise this doesnt fully answer the question with regards doing it within cmake, but I faced a similar problem and thought I should share my solution. Is there a simple variable I'm overlooking that I could put in my toolchain file's CMAKE_C_FLAGS like -Wa,-alh=$.A list of compile definitions to use when building against the library.Ī list of definitions to use when building against the library.Ī string of flags to use when building executables against the library.Ī boolean that describes whether the module was found successfully.Ī list of include directories to use when building against the library. Get_filename_component(curr_name TestExe NAME_WM)Īs expected, this prints TestExe instead of the hoped for main I've looked at the get_filename_component command, but it appears only to get the filename of the output: add_executable(TestExe main.c) I can't figure out how to get CMake to use the current filename without the extension to save the file. The current build system, when building a file called main.c passes -Wa,-alh=.\CortexM0\ARM_GCC_493\Debug/main.lst as an argument to gcc. I'm having some trouble figuring out how to generate list files for each dependency of my executable target. I'm trying to emulate a binary build manager for an embedded Cortex-M0 target using a CMake project. I hope this is a simple question and I'm just missing something fundamental.
