You should look at the compile/link lines.   First I would look at the 
link lines:

This is the qmake one:

qcc -Vgcc_ntoarmv7le -lang-c++ 
-Wl,-rpath-link,/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/lib 
-Wl,-rpath-link,/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib 
-Wl,-rpath-link,/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib/qt4/lib 
-o o.le-v7-g/WikiReader o.le-v7-g/.obj/main.o o.le-v7-g/.obj/wikimodel.o 
o.le-v7-g/.obj/moc_wikimodel.o 
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/lib 
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib -L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6/armle-v7/usr/lib/qt4/lib 
-L/home/taylor/Development/bbndk/target_10_0_9_2318/qnx6//usr/lib/qt4/lib -lbbcascades 
-lQtDeclarative -lQtScript -lQtSvg -lQtSql -lsqlite3 -lz -lQtXmlPatterns 
-lQtGui -lQtXml -lQtNetwork -lsocket -lQtCore -lm -lbps


This is the cmake one:

/opt/bbndk/host_10_0_9_404/linux/x86/usr/bin/ntoarmv7-c++   -Wall -fPIC 
-Wall -fPIC -g3 -ggdb -O0    CMakeFiles/wikireader.dir/main.cpp.o

CMakeFiles/wikireader.dir/qrc_wikireader.cxx.o 
CMakeFiles/wikireader.dir/wikireader_automoc.cpp.o  -o wikireader 
/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtCore.so 
/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtNetwork.so 
/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtXml.so 
/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtGui.so 
/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib/libQtDeclarative.so 
-lbbcascades 
-Wl,-rpath,/opt/bbndk/target_10_0_9_1673/qnx6/armle-v7/usr/lib/qt4/lib



Right off the bat they are using different compilers to link.   I would 
try to get the CMake one to match the qmake one by hand and see if you 
can fix the problem.  Once you figure out the magic command line that 
makes it work, then we can figure out how to get CMake to produce the 
same command line.

BTW, same thing with the compile lines.  CMake does c++ and qmake does 
gcc -lang-c++.
