[CMake] VC8 projects generated multiple times

[Laurentiu Nicolae]

Hi all,

I am trying to generate VC8 solutions and projects for our software. I
currently have the folowing setup:

* A bunch of DLLs, each with its own VCProj
* Six solutions that share some (but not all) of these DLLs.

I am using the CMake command PROJECT to specify the solutions, and
ADD_SUBDIRECTORY(${dll_dir}) for all the DLLs that belong to that
particular solution. Which leads to the fine situation of having the DLL
directories processed six time in a row. That's over 5 minutes of
generation time for our projects - as compared to 1 minute if I only
generate the umbrella (All) project with all the DLLs. Either CMake or I
must be doing something wrong ;)

It must be said that I generate the list of files in the projects with
GLOB_RECURSIVE. That might have something to do with it. Not using this
is out of the question - we adopted CMake to be able to regenerate
changing workspaces as a prime requirement; cross-compilation is still
important, but falls under "added benefits" for us.

Any ideas on how to solve this problem would be appreciated.

Cheers,
Laurentiu
