Installing Chrono (C++)

[Henry Mr.]

hello all!

  In install Core Chrono module,In the 6th step, when running cmake, I don’t know how to solve the problem on the picture. I want to know if I downloaded eigen and whether I need to put the file specified by it in the specified location, or if there are other decisive measure。thinks！

Hi Henry,
sometimes (but I don't remember why) you need to specify the location of the Eigen library through the EIGEN3_INCLUDE_DIR variable that is not shown by default in CMake.
So, please click on Add Entry and specify it manually, like this:

BTW, it was also written in the guide: 

• Specify the location of the Eigen installation. If this is not detected automatically, you may need to manually set the CMake variable EIGEN3_INCLUDE_DIR.
  For example, C:/workspace/libraries/eigen-3.3.7.
