CMake with Qt4 CMake - the cross-platform, open-source build system. CMake is a family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. QMake support in Qt6? Customer still need to build QMake projects; Idea: Make QMake build outside qtbase.git Do a verbatim copy of mkspecs for Qt6; Let CMake generate the QMake module.pri files (via ECM's CMake modules) Qt Community: How do we communicate the progress to our community and get a community decision on the build system for Qt 6? Now, this file is big and scary, so I've been slowly working through it to find analogous functionality between cmake and qmake. However, I'm stuck. I can't seem to wrap my head around how I would convert the following bit over: CONFIG += clatest # Add support for c17. CMake is an open-source, cross-platform family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice.
CMake automates the configuration of build systems. It controls the software compilation process by using simple configuration files, called
CMakeLists.txt files. CMake generates native build configurations and workspaces that you can use in the compiler environment of your choice.
You can use CMake from Qt Creator to build applications for the desktop and Android devices. You can also build single files to test your changes.
Qt Creator automatically detects the CMake executable specified in the
PATH. You can add paths to other CMake executables and use them in different build and run kits.
CMake documentation is installed in Qt help file format (.qch) when you install CMake. It is automatically registered by Qt Creator, and you can view it in the Help mode.
Qmake To Cmake
Qt Creator automatically runs CMake to refresh project information when you edit a
CMakeLists.txt configuration file in a project. Project information is also automatically refreshed when you build the project.
The File System section in the sidebar Projects view displays information from the file system. Qt Creator cannot determine whether the files are part of the project. For example, header files that Qt Creator finds in the project directories but that are not mentioned in the CMakeLists.txt files are listed here.
Adding CMake Tools
Qt Creator requires CMake's file-based API. Please make sure to use CMake version 3.14, or later.
To view and specify settings for CMake:
- Select Tools > Options > Kits > CMake.
- The Name field displays a name for the CMake installation.
- The Path field displays the path to the CMake executable.
- The Help file field displays the path to the CMake help file (.qch) provided by and installed with CMake.
- Deselect the Autorun CMake check box if you do not want to automatically run CMake every time when you save changes to
- Select the Auto-create build directories check box to initially configure the project in a temporary directory. When you build the project Qt Creator starts from scratch and configures the project again using the build directory.
- Select Apply to save your changes.
To add a path to a CMake executable that Qt Creator does not detect automatically, and to specify settings for it, select Add. To make changes to automatically detected installations, select Clone.
Qt Creator uses the default CMake if it does not have enough information to choose the CMake to use. To set the selected CMake executable as the default, select Make Default.
To remove the selected CMake executable from the list, select Remove.
Select the Kits tab to add the CMake tool to a build and run kit. The kit also specifies the CMake generator that is used for producing project files for Qt Creator and the initial configuration parameters:
For more information, see Adding Kits.
Editing CMake Configuration Files
To open a CMakeLists.txt file for editing, right-click it in the Projects view and select Open With > CMake Editor.
You can also use the
cmo filter in the locator to open the CMakeLists.txt file for the current run configuration in the editor. This is the same build target as when you select Build > Build for Run Configuration.
The following features are supported:
- Pressing F2 when the cursor is on a filename to open the file
- Keyword completion
- Code completion
- Path completion
- Matching parentheses and quotes
Qmake Cmake Qbs
Adding External Libraries to CMake Projects
Through external libraries, Qt Creator can support code completion and syntax highlighting as if they were part of the current project or the Qt library.
Qmake Vs Cmake
Qt Creator detects the external libraries using the
find_package() macro. Some libraries come with the CMake installation. You can find those in the
Modules directory of your CMake installation. For more information, see cmake-packages(7).
Syntax completion and highlighting work once your project successfully builds and links against the external library.
