@ -57,7 +57,23 @@ A few options (--qt{dir,bin,...}) and environment variables
(QT5_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
tool path selection, etc; please read the source for more info.
The detection uses pkg-config on Linux by default. To force static library detection use:
The detection uses pkg-config on Linux by default. The list of
libraries to be requested to pkg-config is formulated by scanning
in the QTLIBS directory (that can be passed via --qtlibs or by
setting the environment variable QT5_LIBDIR otherwise is derived
by querying qmake for QT_INSTALL_LIBS directory) for shared/static
libraries present.
Alternatively the list of libraries to be requested via pkg-config
can be set using the qt5_vars attribute, ie:
conf.qt5_vars = ['Qt5Core', 'Qt5Gui', 'Qt5Widgets', 'Qt5Test'];
This can speed up configuration phase if needed libraries are
known beforehand, can improve detection on systems with a
sparse QT5 libraries installation (ie. NIX) and can improve
detection of some header-only Qt modules (ie. Qt5UiPlugin).
To force static library detection use:
QT5_XCOMPILE=1 QT5_FORCE_STATIC=1 waf configure
