\title Setting Up a CMake Project
CMake is an alternative to qmake for automating the generation of build
configurations. 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.
Since \QC 1.1, CMake configuration files are supported. Since \QC 1.3, the
Microsoft tool chain is supported if the CMake version is at least 2.8.
\section1 Setting the Path for CMake
You can set the path for the \c CMake executable in \gui{Tools} >
\gui{Options > Build & Run > CMake}.
\image qtcreator-cmakeexecutable.png
\note Before you open a \c CMake project, you must modify the \c{PATH}
environment variable to include the bin folders of \c mingw and Qt.
For instance, if the Qt 4 SDK is installed in \c {C:\SDK}, you would use the
following command to set the environment variables in the command line
prompt:
\code
set PATH=C:\sdk\mingw\bin;C:\sdk\qt\bin;
\endcode
Then start \QC by typing:
\code
C:\sdk\bin\qtcreator.exe
\endcode
\section1 Opening CMake Projects
To open a \c CMake project:
\list 1
\o Select \gui{File} > \gui{Open File or Project}.
\o Select the \c{CMakeLists.txt} file from your \c CMake project.
\endlist
A wizard guides you through the rest of the process.
\note If the \c CMake project does not have an in-place build, \QC
lets you specify the directory in which the project is built
(\l{glossary-shadow-build}{shadow build}).
\image qtcreator-cmake-import-wizard1.png
The screenshot below shows how you can specify command line arguments to
\c CMake for your project.
\image qtcreator-cmake-import-wizard2.png
Normally, there is no need to pass any command line arguments for projects
that are already built, as \c CMake caches that information.
\section1 Building CMake Projects
\QC builds \c CMake projects by running \c make, \c mingw32-make, or
\c nmake depending on your platform. The build errors and warnings are
parsed and displayed in the \gui{Issues} output pane.
By default, \QC builds the \bold{all} target. You can specify which
targets to build in \gui{Project} mode, under \gui{Build Settings}.
\image qtcreator-cmake-build-settings.png
\QC supports multiple build configurations. You can change the build
directory after the initial import.
\section1 Running CMake Projects
\QC automatically adds \gui{Run Configurations} for all targets specified
in the \c CMake project file.
For more information about known issues for the current version, see
\l{Known Issues}.
\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 FindFoo.cmake file. For more information, see
\l{http://vtk.org/Wiki/CMake_FAQ#Writing_FindXXX.cmake_files}{CMake FAQ}.
Syntax completion and highlighting work once your project successfully
builds and links against the external library.
