# This got a bit gross... For multi-configuration generators the target
# properties return the resolved value of the string, not the build system
# expression. To reconstruct the platform-agnostic path we have to do some
# magic. First we grab one of the types, and a type-specific path. Then from
# the type-specific path we find the last occurrence of the type in the path,
# and replace it with CMAKE_CFG_INTDIR. This allows the build step to be type
# agnostic again.
