There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
"reactos-cov\modules\rostests\winetests\msi\msi_winetest.rc(2): error RC2135: file not found: custom.dll [C:\ros_build\modules\rostests\winetests\msi\msi_winetest.vcxproj]".
Output files are written to Debug\ and Release\ subfolders in VSSolution mode, so the RC compiler will only find custom.dll if it knows to look in the right folder.
