Using SYSROOT in .pro file

[vikramg]

Is sysroot accessible via some predefined environment variable in the .pro file? I would like to specify library path on the target using the sysroot, e.g.:

LIBS += -L$${SYSROOT}/my/lib/location -lmisc

I tried using QT_SYSROOT which does have the value that I want, but that doesn't seem to work in the pro file. Can the qmake variables not be used?

Hi,

IIRC, you have to use square brackets to get such a property from qmake itself.

Thanks, that works! Use as follows:

LIBS += -L$$[QT_SYSROOT]/my/lib/location -lmisc

Official documentation here: http://doc.qt.io/qt-5.9/qmake-language.html (See "Accessing qmake Properties".)
