IAR IDE shows that Fatal Error[Li001]: could not open file ideprojects\iar\library\prebuilt\libnmsis_dsp_rv32imafdc.a

Firstly， I clone respository according https://github.com/Nuclei-Software/NMSIS/blob/master/NMSIS/ideprojects/iar/README.md， but when open nmsis_dsp_examples.eww by IAR IDE， then build the examples，it fails：

[dongyongtao]

The library used by IAR nmsis dsp examples located in $PROJ_DIR$\..\library\prebuilt\libnmsis_dsp_rv32imafdc.a，so you should：

1. Click nmsis_library.eww， build the library.（the generated library with .a suffix is placed in Your path\NMSIS\NMSIS\ideprojects\iar\library\Debug\Exe called nmsis_dsp.a, and nmsis_nn.a, which is respectively ready for the nmsis_dsp_examples and nmsis_nn_examples projects.）
2. Create a directory called "prebuilt" in Your path\NMSIS\NMSIS\ideprojects\iar\library
3. Copy and rename nmsis_dsp.a to libnmsis_dsp_rv32imafdc.a, put it in the Your path\NMSIS\NMSIS\ideprojects\iar\library\prebuilt
4. Rebuild the nmsis dsp examples
5. Deal the same with nmsis nn examples
