just to make sure, I did all you suggested again, but I still end up with linker errors, although there are this far more than before:
LINK : fatal error LNK1104: cannot open file '..\..\..\lib\Debug\vil.lib'
On a positive note, the vbl.lib, vpl.lib and vul.lib were built automatically this time.
Everything was straight out of the box, in a brand new directory, with the build directory being different, no changes to the code or in CMake (just ran Configure, then Generate), loaded the resulting vxl.sln and clicked on Build ALL_BUILD.
Given the size of the error log (80KB), I will not post it here but will send you a copy directly in a minute.
