When loading a package configuration file, find_package defines variables to provide information about the call arguments. In particular, CMAKE_FIND_PACKAGE_NAME represents the package name.
This PR uses this variable instead of a hardcoded name, making the use case suggested in https://github.com/chaincodelabs/libmultiprocess/pull/98#issuecomment-2243751206 workable:
find_package(Libmultiprocess COMPONENTS Lib)
find_package(LibmultiprocessNative COMPONENTS Bin
NAMES Libmultiprocess
)
