add cmake external project for eigen 8 years ago			`INCLUDE(ExternalProject)`

			`SET(EIGEN_SOURCE_DIR ${THIRD_PARTY_PATH}/eigen3)`

Demostration of cmake refine for HIP support. 1. Add option WITH_AMD_GPU. 2. Add cmake/hip.cmake for HIP toolchain. 3. Some external module such as eigen may need HIP port. 4. Add macro hip_library/hip_binary/hip_test to cmake/generic.cmake. 5. Add one HIP source concat.hip.cu as an example. Each .cu may have its corresponding .hip.cu. 7 years ago			`INCLUDE_DIRECTORIES(${EIGEN_SOURCE_DIR}/src/extern_eigen3)`
