[SOLVED] CMake Error, "Eigen3_DIR" not found

Dear SOFA support,

I tried to build SOFA V15.12 with visual studio 2010 on 64-bit win 7, but the cmake reported the following errors:

CMake Error at SofaFramework/CMakeLists.txt:169 (find_package):
By not providing “FindEigen3.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “Eigen3”, but
CMake did not find one.

Could not find a package configuration file provided by “Eigen3” with any
of the following names:

Eigen3Config.cmake
eigen3-config.cmake

Add the installation prefix of “Eigen3” to CMAKE_PREFIX_PATH or set
“Eigen3_DIR” to a directory containing one of the above files. If “Eigen3”
provides a separate development package or SDK, be sure it has been
installed.

I had already copied and pasted win-dependence and QT4.8.3 files before using cmake.

How to solve this issue ?

Best regards,
Weng Bin
