fixes some variables in CppInterOpconfig.cmake.in file

[anutosh491]

This was discovered while building xeus-cpp . We have the following in xeus-cpp

find_package(CppInterOp ${CppInterOp_REQUIRED_VERSION} REQUIRED)
if(CppInterOp_FOUND)
  message(STATUS "Found CppInterOp: config=${CPPINTEROP_CONFIG} dir=${CPPINTEROP_DIR} (found version=${CPPINTEROP_VERSION} compatible with Clang ${CPPINTEROP_LLVM_VERSION_MAJOR}.x)")
endif()

which ends up being

Found CppInterOp: config= dir= (found version= compatible with Clang 19.x)

So CPPINTEROP_CONFIG , CPPINTEROP_DIR, CPPINTEROP_VERSION are empty but CPPINTEROP_LLVM_VERSION_MAJOR has "19.x"

After this we could have

message(STATUS "Found CppInterOp: config=${CPPINTEROP_CMAKE_DIR} dir=${CPPINTEROP_INSTALL_PREFIX} (found version=${CPPINTEROP_LLVM_PACKAGE_VERSION} compatible with Clang ${CPPINTEROP_LLVM_VERSION_MAJOR}.x)")

Gentle ping. I think this should be ready. Pretty small change. Can be seen while building xeus-cpp that cmake dir is not set correctly. This PR fixes that
