[CMake] Fwd: TARGET_LINK_LIBRARIES not working for MSVC

[Avanindra Singh]

Hi Eric,

Thanks for the reply. It was very useful. I incorporated the changes you
mentioned. I removed all the link_libraries macros
from the projects. Also I changed camke_minimum_version to 2.6 . I have
CMake 2.8 in both windows as well as Linux. Though
I am still getting the same errors.I would strip the project down to one or
two lib and I would get back with the results.

Though one point I would like to mention, the linker problem is coming for
all the libraries in project added through
ADD_LIBRARY macro. While the linker is produced correct to target added with
ADD_EXECUTABLES. I had only one
executable in my whole project and it is in the root CMakeLists.txt. When I
remove the main.cpp from ADD_EXECUTABLES
and replace it with ADD_LIBRARY, I get linker error for root too, again no
linker is generated for ADD_LIBRARY target.

For the find_package macro as you mentioned, it worked for BOOST and OPenCV
but did not find ImageMagick, so I hardcoded
the includes and Libraries.

Regards
Avanindra
