\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 supports CMake version 3.0, or later. For best results you should use
CMake version 3.7.2 with server-mode support, or later. Earlier versions
provide less information to the code model, which will then fail to resolve
includes and defines.
For CMake version 3.14, or later, \QC supports the
\l {https://cmake.org/cmake/help/latest/manual/cmake-file-api.7.html}
{file-based API}.
To specify paths to CMake executables:
\list 1
\li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits >
\uicontrol CMake > \uicontrol Add.
\image qtcreator-cmakeexecutable.png
\li In the \uicontrol Name field, specify a name for the tool.
\li In the \uicontrol Path field, specify the path to the CMake
executable.
\li In the \uicontrol {Help file} field, specify the path to the
CMake help file (.qch) provided by and installed with CMake.
\li Select the \uicontrol {Auto-create build directories} check box to
automatically create build directories for CMake projects.
\li Select \uicontrol Apply to save your changes.
\endlist
\note When the \uicontrol {Autorun CMake} check box is enabled, \QC
automatically runs CMake when you make changes to \c {CMakeLists.txt} files.
We recommend that you do not disable this check box, because that would
eventually make \QC and the project disagree on what the project information
is.
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 configuration variables that are used:
\image qtcreator-kits.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.
\note If you provide your own libraries, you also need to provide your own
\c {FindXXX.cmake} file. For more information, see
\l{https://gitlab.kitware.com/cmake/community/wikis/FAQ#writing-findxxxcmake-files}
{Writing FindXXX.cmake files}.
Syntax completion and highlighting work once your project successfully
builds and links against the external library.
