OpenCV 4.1.2+VS17+Anaconda 3+Win10+[Win32!!]

Try to build 32 bit OpenCV library using the same scripts from previous time
OpenCV 4.1.2 with VS17 on Win10 with Anaconda 3 - Let’s see this time…

Results

• “INstallation” folder not build (i.e. not installed) because no 64 bit hdf5.lib (see below). The script apparently requires ALL opencv modular library built successfully before proceeding to installation stage.
• ALL other libraries built successfully except HDF5 test

Errors

1. hdf5.lib from Anaconda is 64 bit (Because I only installed 64 bits Anaconda)

• Downloaded Anaconda3-5.3.1-Windows-x86_64.exe on 28/11/2018 15:25
