CMake error: source directory does not appear to contain CMakeLists.txt

[arne-cl]

Dear @yunan4nlp,

when I try to build the software according to the README, I get this error:

/opt/NNDisParser/build # cmake .. -DEIGEN3_DIR=${path}eigen -DN3L_DIR=${path}N3LDG -DMKL=TRUE
CMake Error: The source directory "/opt/NNDisParser" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

If I copy CMakeLists.txt from /opt/NNDisParser/eigen to /opt/NNDisParser/,
the error becomes:

CMake Error at CMakeLists.txt:35 (file):
  file failed to open for reading (No such file or directory):

    /opt/NNDisParser/Eigen/src/Core/util/Macros.h


CMake Warning at CMakeLists.txt:71 (find_package):
  By not providing "FindStandardMathLibrary.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "StandardMathLibrary", but CMake did not find one.

  Could not find a package configuration file provided by
  "StandardMathLibrary" with any of the following names:

    StandardMathLibraryConfig.cmake
    standardmathlibrary-config.cmake

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


CMake Error at CMakeLists.txt:81 (message):
  Can't link to the standard math library.  Please report to the Eigen
  developers, telling them about your platform.
