\title qmake Build Configuration
\image qtcreator-projectpane.png "qmake build settings"
By default, \QC builds qmake projects in a separate directory from the
source directory, as \l{glossary-shadow-build} {shadow builds}. This
keeps the files generated for each \l{glossary-buildandrun-kit}
{build and run kit} separate. If you only build and run with a single
\l{glossary-buildandrun-kit}{kit}, you can deselect the
\uicontrol {Shadow build} checkbox. Select the build directory in the
\uicontrol {Build Directory} field.
To make in-source builds the default option for all projects, select
\uicontrol Edit > \uicontrol Preferences > \uicontrol {Build & Run} >
\uicontrol {Default Build Properties}, and enter a period (.) in the
\uicontrol {Default build directory} field.
In the \uicontrol {Tooltip in target selector} field, you can enter text
that is displayed as a tooltip when you hover the mouse over the build
configuration in the \l{Building for Multiple Platforms}{kit selector}.
You can create separate versions of project files to keep platform-dependent
code separate. You can use qmake \l{Adding Platform Specific Source Files}
{scopes} to select the file to process depending on which platform qmake is
run on.
If debug info is being generated, you can have it placed into separate
files, rather than embedded into the binary, by selecting
\uicontrol Enable in the \uicontrol {Separate debug info} field. For
more information, see \l{Using the Performance Analyzer}. To use default
settings, select \uicontrol {Leave at Default}.
In the \uicontrol {qmake system() behavior when parsing} field, you can
select whether processes are run via qmake's \c system() function or
ignored. Setting this option to \uicontrol Ignore might help if opening
or closing projects takes too long, but it might produce inexact parsing
results.
\section1 Global qmake Settings
To specify settings for all qmake builds, select \uicontrol Edit
> \uicontrol Preferences > \uicontrol {Build & Run} >
\uicontrol Qmake.
\image qtcreator-build-settings-qmake.png "qmake build and run options"
To set the default build properties, select \uicontrol Edit
> \uicontrol Preferences > \uicontrol {Build & Run} >
\uicontrol {Default Build Properties}.
\image qtcreator-build-settings-default.png "default build options"
\section1 Compiling QML
You can compile QML source code into the final binary to improve the
startup time of the application and eliminate the need to deploy QML
files together with the application. For more information, see
\l{Ahead-of-Time Compilation}.
\QC project wizard templates create Qt Quick projects that can be compiled
because they are set up to use the Qt Resource System. To compile QML code,
select \uicontrol Enable in the \uicontrol {Qt Quick Compiler} field. To
use default settings, select \uicontrol {Leave at Default}.
You can specify default behavior for compiling QML code in \uicontrol Edit
> \uicontrol Preferences > \uicontrol {Build & Run} > \uicontrol Qmake >
\uicontrol {Use qmlcachegen}.
\section1 qmake Build Steps
\QC builds qmake projects by running the \c make or \c nmake command from
the Qt version defined for the current build configuration.
\image qtcreator-build-steps.png "Build steps"
To override the shell command that \QC constructs by default, disable or
remove the build step and add a custom build step that specifies another
shell command.
By default, \QC uses all the CPU cores available to achieve maximum build
parallelization. On Linux and \macos, you can specify the number of parallel
jobs to use for building in the \uicontrol {Parallel jobs} field. Select the
\uicontrol {Override MAKEFLAGS} check box to override existing MAKEFLAGS
variables.
Select \uicontrol {Disable in subdirectories} to execute the build step
only for a top-level build.
Select \uicontrol {Add Build Step} > \uicontrol {IncrediBuild for Linux} or
\uicontrol {IncrediBuild for Windows} to accelerate builds by using
\l{IncrediBuild Build Configuration}{IncrediBuild}.
Select \uicontrol {Add Build Step} > \uicontrol {Run Conan Install} to use
the \l{Conan Build Configuration}{Conan} package manager with qmake
