I tried the following:
   $ /gnu/store/p7qc46d0a0kksqlrk9jp9368d85w5980-profile/bin/qmake -d -o cfgtest_QtWebKit.mk cfgtest_QtWebKit.pro

The very lengthy output contains something like this:

When I then look at
/gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/mkspecs/modules/qt_lib_webkit.pri
it contains exactly this information:
QT.webkit.VERSION = 5.212.0
QT.webkit.MAJOR_VERSION = 5
QT.webkit.MINOR_VERSION = 212
QT.webkit.PATCH_VERSION = 0
QT.webkit.name = QtWebKit
QT.webkit.module = Qt5WebKit
QT.webkit.DEFINES = QT_WEBKIT_LIB
QT.webkit.includes = "/gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/include" "/gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/include/QtWebKit"
QT.webkit.private_includes =
QT.webkit.libs = "/gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/lib"
QT.webkit.rpath = "/gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/lib"
QT.webkit.depends = core gui network
QT.webkit.run_depends = sensors positioning qml quick core_private gui_private
QT.webkit.bins = /gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/bin
QT.webkit.libexec =
QT.webkit.plugins =
QT.webkit.imports =
QT.webkit.qml =
QT.webkit.frameworks =
QT.webkit.module_config = v2
QT_MODULES += webkit
QMAKE_LIBS_PRIVATE +=
QMAKE_RPATHDIR += /gnu/store/7xfg1s783krjwrp8xmh2nywl7v4x0pq4-qtwebkit-5.212.0-alpha2/lib

So somehow we need to tell qmake where to search for the .pri files for qtwebkit.
