[Insight-users] CMakeLists.txt and QT

[Iordanescu, Gheorghe (CC/DRD)]

Hello,

I am new to ITK and Cmake.

I work on a Windows machine (Win 2K, SP 2) with Visual C 6.0 (SP5). Here is
my problem:

I tried one example using the following CMakeLists.txt file:
-------------------------------------------------------
PROJECT(TESTPRJ)
INCLUDE_DIRECTORIES(
$(ITK_SOURCE_DIR)\
$(ITK_SOURCE_DIR)/Code/Common
$(ITK_SOURCE_DIR)/Code/IO
$(ITK_SOURCE_DIR)/Code/BasicFilters
$(ITK_SOURCE_DIR)/Code/Algorithms
$(ITK_SOURCE_DIR)/Code/Numerics/vxl
$(ITK_SOURCE_DIR)/Code/Numerics/vxl/vcl
)

LINK_DIRECTORIES(
$(ITK_SOURCE_DIR)\
$(ITK_SOURCE_DIR)/Code/Common
$(ITK_SOURCE_DIR)/Code/IO
$(ITK_BINARY_DIR)/Code/BasicFilters
$(ITK_BINARY_DIR)/Code/Algorithms
$(ITK_BINARY_DIR)/Code/Numerics/vxl
$(ITK_BINARY_DIR)/Utilities/png
$(ITK_BINARY_DIR)/Utilities/zlib
)

LINK_LIBRARIES (
ITKBasicFilters
ITKCommon
ITKIO
VXLNumerics
itkpng
itkzlib
)

ADD_EXECUTABLE(TESTPRJ triDOpening pgm_reader.cpp)
----------------------------------------------------------

In the same directory I have 5 files:
general.h, pgm_reader.cpp, pgm_reader.h, triDOpening.cxx

Everything worked great. I was able to build and run the generated dsp file
(I just loaded the dsw file in Visual C and it worked).

Next I wanted to do the same thing, except I wanted to have the dsp in a
different directory.

So I build the next structure:
someDir/src/ Morphology

In someDir I put the next CMakeLists.txt :

-------------------------------------------------------
PROJECT (ctccad)
SUBDIRS(
src/Morphology
)
INCLUDE_DIRECTORIES(
$(ITK_SOURCE_DIR)\
$(ITK_SOURCE_DIR)/Code/Common
$(ITK_SOURCE_DIR)/Code/IO
$(ITK_SOURCE_DIR)/Code/BasicFilters
$(ITK_SOURCE_DIR)/Code/Algorithms
$(ITK_SOURCE_DIR)/Code/Numerics/vxl
$(ITK_SOURCE_DIR)/Code/Numerics/vxl/vcl
)

LINK_DIRECTORIES(
$(ITK_SOURCE_DIR)\
$(ITK_SOURCE_DIR)/Code/Common
$(ITK_SOURCE_DIR)/Code/IO
$(ITK_BINARY_DIR)/Code/BasicFilters
$(ITK_BINARY_DIR)/Code/Algorithms
$(ITK_BINARY_DIR)/Code/Numerics/vxl
$(ITK_BINARY_DIR)/Utilities/png
$(ITK_BINARY_DIR)/Utilities/zlib
)

LINK_LIBRARIES (
ITKBasicFilters
ITKCommon
ITKIO
VXLNumerics
itkpng
itkzlib
)
-------------------------------------------------------

And in someDir \src\Morphology
I put the same files as above:
general.h, pgm_reader.cpp, pgm_reader.h, triDOpening.cxx
plus the next CMakeLists.txt :

ADD_EXECUTABLE(ctccad triDOpening pgm_reader)

When I tried to build the generated ctccad.dsw file I got the next error
messages:

Also I would like to ask if anybody can provide me some examples of adding
compilation of QT files to cmake (I guess I should use QT_WRAP_CPP command).

Any help will be highly appreciated. 
Thank you in advance,

George
