   Exporting targets is to generate configuration files which used by find_package(). However, msgpack_cpp is a header-only library that cannot be processed by find_package(), so there is no need to export targets.

   Providing a package configuration file with an exported target for header-only libraries is stil possible through INTERFACE libraries. (and provides for easy use of the library: finding correct include directory (if not installed to standard system prefix or include directories), propagate transitive dependencies, setting compiler options, etc...):

   Usage:

   project(SomeMsgpackCxxProject CXX)
   
   find_package(msgpackcxx REQUIRED)
   
   add_executable(${PROJECT_NAME} main.cpp)
   target_link_libraries(${PROJECT_NAME} msgpackcxx)

   I will set up a draft pull request with a preliminary proposal.
