MSVC Community Edition is the new free (as in beer) edition of MSVC, replacing the Express Edition.
I get the following error with Eigen 3.2.4:
CMake error : File <...>/Eigen3-build/DartConfiguration.tcl does not exist. [<...>\Eigen3.vcxproj]
CMake Error at cmake/EigenConfigureTesting.cmake:44 (configure_file):
configure_file Problem configuring file
Call Stack (most recent call first):
Calling cmake with "-DBUILD_TESTING=OFF" does not help, surprisingly.
