[CMake] VisualStudio 7.1 projects

[Dekeyser, Kris]

Hi,

I'm a VS 6 user myself, but I think I can answer a couple of your questions
nevertheless.

- The answer may depend on what you want to achieve. The output directory is
what you specify as LIBRARY_OUTPUT_PATH and EXECUTABLE_OUTPUT_PATH.
CMake/MsDev puts the build type dir after it to allows for multiple build
types to coexist. If that's not ok for you, you can always move or copy the
generated target in a POST_BUILD ADD_CUSTOM_COMMAND. But make sure the next
targets to build can still find the targets it depends on.

- Yes, we had the exactly the same problem. For link libraries, CMake
provides the debug/optimized option to TARGET_LINK_LIBRARIES and that works
fine. Unfortunately there is no such option for LINK_DIRECTORIES and
INCLUDE_DIRECTORIES. You can solve the LINK_DIRECTORIES problem by adding
the full path to the library name in TARGET_LINK_LIBRARIES. I could not find
any way to solve the INCLUDE_DIRECTORIES problem than to create single-build
MsDev projects. I have added a FAQ for this to the CMake Wiki pages. It's
for VS6 and requires some effort. For VS7 it should be as easy as setting
the CMAKE_CONFIGURATION_TYPES to a single value(Debug/Release/...). This
means that you will have a separate build tree for each single configuration
type - exactly like what you would do with Makefile based builds.

- You can access environment variables with $ENV{varname}

- ADD_DEPENDENCIES should only be used for exceptions. Use
TARGET_LINK_LIBRARIES instead.

Best regards, Kris.
