[CMake] Linking against libraries under windows

[Christian Lohr]

Hello,

I need to include libraries for linking against OpenCascade in my
CMakeLists.txt. Everything went fine for Debian Linux, but I don’t get
it working under windows. And I've got another question about this
linking. I didn't get it working that "FIND_LIBRARY(OPENCASCADE_LIB
TKernel TKMath TKSTEP ... )" and a following
"TARGET_LINK_LIBRARIES(triangulation ${OPENCASCADE_LIB}) would link
against all those libraries. It seemed that it only linked against
TKernel, and omitted the rest. Under windows a environment variable is
set, called CASROOT, usually pointing to C:\OpenCASCADE6.3.0\, is
there a way getting cmake to use this path variable. The Libs under
windows are under ${CASROOT}/win32/lib, and the includes are under
${CASROOT}/inc.

Yours sincerely,

Christian Lohr
