qmake adding header files from subfolders - c++

Question

I am trying to generate a c++ project using qmake and compiling it under visual studio.
this project as a dependency to itk.
I made a .pri with a MyITK project in it:
MyITK {
CONFIG_FOUND += MyITK
INCLUDEPATH += $${PACKAGE_SOURCES}/Shared/MyITK
QMAKE_LIBDIR += $${PACKAGE_LIB}/MyITK
win32:LIBS += ITKIONIFTI-4.13.lib \
ITKCommon-4.13.lib \
ITKBiasCorrection-4.13.lib \
ITKBioCell-4.13.lib \
etc
in the .pro of my project is like that:
CONFIG += staticlib MyITK
HEADERS += \
myowncode.h \
myowncode2.h \
myowncode3.h \
SOURCES += \
myowncode.cpp \
myowncode2.cpp \
when I try to compile my project, it find the .h only if I put them directly in $${PACKAGE_SOURCES}/Shared/MyITK
if I "copy past" the source code form itk, which is organized like that:
/Modules/ModuleNames/SubModulesNames/include
is there a way to make QMake looking for .h in all subdirectories ?
according to Matt answers I tried:
ITKModules = Core Filtering IO Numerics Registration Segmentation
Core.submodules = Common FiniteDifference
IO.submodules = NIFTI ImageBase
Numerics.submodules = Eigen FEM NarrowBand NeuralNetworks
Registration.submodules = Common FEM
Segmentation.submodules = BioCell ConnectedComponents KLMRegionGrowing
MyITK {
CONFIG_FOUND += MyITK
for(foo, ITKModules): for(bar, $${foo}.submodules) {
INCLUDEPATH += $${PACKAGE_SOURCES}/Shared/MyITK/Modules/$${foo}/$${bar}/include
}
QMAKE_LIBDIR += $${PACKAGE_LIB}/MyITK
win32:LIBS += ITKIONIFTI-4.13.lib \
ITKCommon-4.13.lib \
ITKBiasCorrection-4.13.lib \
ITKBioCell-4.13.lib \
}
but it still can't link to the .h at VS compilation.

Actually you're trying to make your compiler look into all subdirectories, not qmake.
qmake itself has no built-in function to generate subdirs list. But you can prettify your pro a bit using loops:
modules = x1 x2 x3
x1.submodules = y1 y4
x2.submodules = y2 y5
x3.submodules = y3 y6
for(foo, modules): for(bar, $${foo}.submodules) {
INCLUDEPATH += /Modules/$${foo}/$${bar}/include
}
