\title Setting Up CMake
CMake automates the configuration of build systems. It controls the software
compilation process by using simple
configuration files, called \c {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 \QC to build applications for the desktop and
Android devices. You can also build single files to test your changes.
\QC automatically detects the CMake executable specified in the \c PATH.
You can add paths to other CMake executables and use them in different
build and run \l{glossary-buildandrun-kit}{kits}.
CMake documentation is installed in Qt help file format (.qch) when you
install CMake. It is automatically registered by \QC, and you can view it
in the Help mode.
\QC automatically runs CMake to refresh project information when you edit
a \c CMakeLists.txt configuration file in a project. Project information is
also automatically refreshed when you build the project.
\section1 Adding CMake Tools
\QC requires CMake's \l{https://cmake.org/cmake/help/latest/manual/cmake-file-api.7.html}
{file-based API}. Please make sure to use CMake version 3.14, or later.
To view and specify settings for CMake:
\list 1
\li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits >
\uicontrol CMake.
\image qtcreator-cmakeexecutable.png
\li The \uicontrol Name field displays a name for the CMake
installation.
\li The \uicontrol Path field displays the path to the CMake
executable.
\li The \uicontrol {Help file} field displays the path to the
CMake help file (.qch) provided by and installed with CMake.
\li Deselect the \uicontrol {Autorun CMake} check box if you do not want
to automatically run CMake every time when you save changes to
\c {CMakeLists.txt} files.
\li Select the \uicontrol {Auto-create build directories} check box to
initially configure the project in a temporary directory. When you
build the project \QC starts from scratch and configures the
project again using the build directory.
\li Select \uicontrol Apply to save your changes.
\endlist
To add a path to a CMake executable that \QC does not detect automatically,
and to specify settings for it, select \uicontrol Add. To make changes to
automatically detected installations, select \uicontrol Clone.
\QC uses the \e {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 \uicontrol {Make Default}.
To remove the selected CMake executable from the list, select
\uicontrol Remove.
Select the \uicontrol 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 \QC and the initial configuration parameters:
\image qtcreator-kits-cmake.png
For more information, see \l {Adding Kits}.
\section1 Editing CMake Configuration Files
To open a CMakeLists.txt file for editing, right-click it in the
\uicontrol Projects view and select \uicontrol {Open With} >
\uicontrol {CMake Editor}.
You can also use the \c cmo filter in the \l {Searching with the Locator}
{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
\uicontrol Build > \uicontrol {Build for Run Configuration}.
The following features are supported:
\list
\li Pressing \key F2 when the cursor is on a filename to open the file
\li Keyword completion
\li Code completion
\li Path completion
\li Auto-indentation
\li Matching parentheses and quotes
\endlist
\section1 Adding External Libraries to CMake Projects
Through external libraries, \QC can support code completion and syntax
highlighting as if they were part of the current project or the Qt library.
\QC detects the external libraries using the \c {find_package()}
macro. Some libraries come with the CMake installation. You can find those
in the \c {Modules} directory of your CMake installation.
For more information, see
\l{https://cmake.org/cmake/help/latest/manual/cmake-packages.7.html}
{cmake-packages(7)}.
Syntax completion and highlighting work once your project successfully
builds and links against the external library.
