For problems like this you just need to read carefully and start debugging.  Does the file VXLLibraryDepends.cmake exist there?  Is it somewhere else?  Did VXL build OK for you?

Thanks for responding! I add this line but CMake gives me the following errors when I configure it:


CMake Error at E:/VXL/VXL_BIN/VXLConfig.cmake:33 (INCLUDE):

include could not find load file:

E:/VXL/VXL_BIN2/VXLLibraryDepends.cmake

Call Stack (most recent call first):

CMakeLists.txt:4 (FIND_PACKAGE)

Configuring incomplete, errors occurred!





What does this mean?



Best regards,

Have a look at section B.1.3 in the VXL book for examples of how to set up your CMakeLists.txt file.  You are missing this line:

FIND_PACKAGE(VXL)

Hi,

I am new to VXL and I just installed it on Windows. I want to test it by building my first project "VXL_HelloWorld" but it failed when building in Visual Studio 2010.

Here is my CMakeLists.txt:

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
PROJECT(VXL_HelloWorld)

IF(VXL_FOUND)
  INCLUDE(${VXL_CMAKE_DIR}/UseVXL.cmake)
ENDIF(VXL_FOUND)

ADD_EXECUTABLE(HelloWorld HelloWorld.cxx )
TARGET_LINK_LIBRARIES( HelloWorld vcl )


And here is my source code:

#include <vcl_iostream.h>
int main()
{
  // send string "hello world" to the standard output stream cout.
  vcl_cout << "Hello world\n";
  return 0;
}


After I use CMake to compile and generate the project, I opened the .sln file and try to build it but it failed and gives the following errors:
Error  1          error C1083: Cannot open include file: 'vcl_iostream.h': No such file or directory
          2          IntelliSense: cannot open source file "vcl_iostream.h"
          3          IntelliSense: identifier "vcl_cout" is undefined


I guess there may be some problem with my CMakeLists.txt.
Could you help me find out the problem?

Thanks and best regards,
Hao Wu
