[Insight-users] Better linking of special headers

[Michael Xanadu]

Hi,

I have a problem linking an ITK class to my project. At first I build the
binaries of ITK 3.20 and linked them to my project via CMAKE. What I did
was:


FIND_PACKAGE(ITK)
IF(ITK_FOUND)
  INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
  MESSAGE(FATAL_ERROR "Cannot build without ITK. Please set ITK_DIR.")
ENDIF(ITK_FOUND)

SET(ITK_LIBS
  ITKAlgorithms
  ITKBasicFilters
  ITKCommon
  ITKIO
)

LINK_LIBRARIES(${ITK_LIBS})


Everything works fine. I can compile my project with many ITK classes in
use. But then I tried to use

#include "itkImageKernelOperator.h"

in my project. Unfortunatelly, the compiler (VS 2010) says:

fatal error C1083: Cannot open include file: 'itkImageKernelOperator.h': No
such file or directory

I found out that the directory C:/Libs/ITK_SRC_3.20.1/Code/Review (with the
missing file mentioned above) of the ITK source was missing in the project
settings. Don't know why. So I added following line to CMakeLists.txt:

INCLUDE_DIRECTORIES(C:/Libs/ITK_SRC_3.20.1/Code/Review)

OK, now it works. The missing file was found by the compiler and everything
is fine now. But of course this line is a little bit ugly because I need to
know the absolute path to the ITK source.
Does anybody know a better looking solution?


With kind regards,
Michael
