Export targets to build tree (#49)

It is insecure and inconvenient to necessitate installing IrrlichtMt to access the target export. A copy of the export is now placed in the build tree during configuration so that it can be directly accessed from any project by pointing find_package() to look at the IrrlichtMt source directory.

cmake . -DBUILD_SHARED_LIBS=OFF
make -j$(nproc)
This will put an IrrlichtMtTargets.cmake file into a cmake/ directory in the current build directory, and it can then be imported from another project by pointing find_package() to the source directory of this project, or by setting the CMAKE_PREFIX_PATH variable to that same path.
