The autocompletion doesn't work if eval(INCLUDE_TARGET != ""): INCLUDEPATH += "$${INCLUDE_TARGET}" is used to set the include path

The attached example can be used to reproduce this issue. If either of those eval() lines (shown below) are used the Qt Creator's editor doesn't find the fakelib library if one hovers over the #include "fakeLib.h" found in the applications main.cpp. Neither the autocompletion does work in that case. So, if one starts typing "testFunc" and presses Ctrl+space, Qt Creator doesn't complete/find the function name.

This works with isEmpty.

qmake adds the include path successfully, but Qt Creator seems not to do so.

INCLUDE_TARGET=fakeLib
eval(INCLUDE_TARGET != ""): INCLUDEPATH += "$${INCLUDE_TARGET}"
#!isEmpty(INCLUDE_TARGET): INCLUDEPATH += "$${INCLUDE_TARGET}"
#eval(!isEmpty(INCLUDE_TARGET)): INCLUDEPATH += "$${INCLUDE_TARGET}"

The reason for this might be in qt-creator\src\shared\proparser\profileevaluator.cpp in "case T_EVAL:". It might be that it fails to parse this:

 
ProFile *pro = m_parser->parsedProBlock(fL1S("(eval)"),                                                      args.join(statics.field_sep));
