Issues with qmake5 PortGroup

[Nicolas Pavillon]

Hi everyone,

Recently, I had issues with updating several qt5 ports, such as qscintilla-qt5 (updated recently), or py37-pyqt5, all related to the qmake5 PortGroup. 

The errors I am experiencing are similar to the one reported in https://trac.macports.org/ticket/58760 <https://trac.macports.org/ticket/58760>, which are:
:debug:configure system:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_github.com_macports_macports-ports_python_py-pyqt5/py37-pyqt5/work/PyQt5_gpl-5.12.2" && /opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 configure.py -q /opt/local/libexec/qt5/bin/qmake --verbose --confirm-license --sip=/opt/local/bin/sip-3.7 --dbus=/opt/local/Library/Frameworks/Python.framework/Versions/3.7/include/python3.7m/dbus-1.0 --designer-plugindir=/opt/local/libexec/qt5/plugins/designer/Py37Qt5 --qml-plugindir=/opt/local/libexec/qt5/plugins/Py37Qt5 --no-qsci-api --disable=QtWebKit --disable=QtWebKitWidgets --no-dist-info --spec=macx-clang
:info:configure Error: Failed to determine the detail of your Qt installation. Try again using
:info:configure the --verbose flag to see more detail about the problem.
:info:configure Querying qmake about your Qt installation...
:info:configure Determining the details of your Qt installation...
:info:configure /opt/local/libexec/qt5/bin/qmake -o cfgtest_QtCore.mk cfgtest_QtCore.pro
:info:configure Project ERROR: Could not resolve SDK Path for 'macosx10.14' using --show-sdk-path
However, I do have the Xcode Tools installed, so that missing tools should not be the problem.

Having looked around, it seems that a particular line in the qmake5 PortGroup is causing the issue. It define the variable QMAKE_MAC_SDK as below, which seems to be the origin of the problem.
puts ${cache} "QMAKE_MAC_SDK=macosx${configure.sdk_version}"
If I suppress this line from the PortGroup, it is then possible to install the related ports without any problem. However, as I did not see many reports about similar issues, I am wondering if this is an actual problem, or an issue specific to my system, although this seems to appear consistently throughout several ports in my case.

Would anyone have an idea on that?

Cheers,

Nicolas
