After changing any configuration value in CMake, you need to regenerate it in order to have an updated VS solution file. Doing a make install is enough if you’re using plain Makefiles, but we’re talking about Microsoft technology here. I wouldn’t be surprised if by building only the INSTALL target fails to incorporate the update. Close VS, change it, regenerate, open the solution in VS, build INSTALL and see what happens. If the binaries go to where you wanted, then it’s ok.
