Coming back to this, turns out the actual problem was somewhat earlier:


[ 14%] Automatic moc for target kded_kcookiejar
Generating kcookieserver.moc
/src/work/pkgsrc/wip/kio/work.x86_64/kio-5.21.0/src/ioslaves/http/kcookiejar/kcookieserver.cpp:0: 
Note: No relevant classes found. No output generated.

resulting in a zero length kcookieserver.moc

After some probing worked out that what cmake was running to generate 
kcookieserver.moc was:

/usr/pkg/qt5/bin/moc 
-I/src/work/pkgsrc/wip/kio/work.x86_64/kio-5.21.0/_KDE_build/src/ioslaves/http/kcookiejar 
-I/src/work/pkgsrc/wip/kio/work.x86_64/kio-5.21.0/src/ioslaves/http/kcookiejar 
-I/usr/pkg/include/KF5/KWindowSystem -I/usr/pkg/include 
-I/usr/pkg/include/KF5 -I/usr/pkg/qt5/include 
-I/usr/pkg/qt5/include/QtWidgets -I/usr/pkg/qt5/include/QtGui 
-I/src/work/pkgsrc/wip/kio/work.x86_64/.buildlink/include 
-I/usr/pkg/qt5/include/QtCore -I/usr/pkg/qt5/./mkspecs/netbsd-g++ 
-I/usr/pkg/include/KF5/KService -I/usr/pkg/include/KF5/KConfigCore 
-I/usr/pkg/include/KF5/KCoreAddons -I/usr/pkg/include/KF5/KDBusAddons

-DQT_NO_DEBUG -DQT_NO_SIGNALS_SLOTS_KEYWORDS 
-DQT_NO_URL_CAST_FROM_STRING -DQT_USE_FAST_OPERATOR_PLUS 
-DQT_USE_QSTRINGBUILDER -DQT_WIDGETS_LIB -DTRANSLATION_DOMAIN="kio5" 
-D_LARGEFILE64_SOURCE -o 
/src/work/pkgsrc/wip/kio/work.x86_64/kio-5.21.0/_KDE_build/src/ioslaves/http/kcookiejar/kcookieserver.moc 
/src/work/pkgsrc/wip/kio/work.x86_64/kio-5.21.0
/src/ioslaves/http/kcookiejar/kcookieserver.cpp

and that if I run the same command with the "-I/usr/pkg/include" removed 
then it works.

However there is too much magic processing going on within cmake to work 
out how to fix this within the package.  Can't see where the 
"-I/usr/pkg/include" is coming from (same package under Linux doesn't 
add it).  Can't see how to modify the arguments to moc or which moc to run.

Any suggestions?
