buildOCV.sh + CLion workaround for OpenCV

buildOCV.sh

#!/bin/bash -e

# Adopted from https://docs.opencv.org/master/d3/d52/tutorial_windows_install.html
#
# Changes:
#  - version fixed to 4.5.1 - https://github.com/opencv/opencv/releases/tag/4.5.1
#  - disabled opencv_contrib
#  - RelWithDebInfo instead of Release
#
# How to use:
# 1) Run git-bash
# 2) mkdir /c/lib
# 3) Save this script to C:/lib/installOCV.sh
# 4) cd /c/lib
# 5) ./installOCV.sh
# 6) CLion: File->Settings->Build, ..->CMake:
#  - Add RelWithDebInfo profile
#  - To both profiles add to CMake options: -DOpenCV_DIR=C:\lib\build_opencv
#  - Right click on the project root->Copy->Absolute path
#  - Edit launch configurations: Working directory: Ctrl+V (i.e. path to project root)
# 7) Try to run test_sift (in both: Debug and RelWithDebInfo) - it will fail
#
# 8) Copy to ...\PhotogrammetryTasks2021\cmake-build-relwithdebinfo these files:
#  - ...\PhotogrammetryTasks2021\cmake-build-relwithdebinfo\bin\gtest_main.dll
#  - ...\PhotogrammetryTasks2021\cmake-build-relwithdebinfo\bin\gtest.dll
#  - C:\lib\install\opencv\x64\vc16\bin\opencv_world451.dll
#
# 9) Copy to ...\PhotogrammetryTasks2021\cmake-build-debug these files:
#  - ...\PhotogrammetryTasks2021\cmake-build-debug\bin\gtest_maind.dll
#  - ...\PhotogrammetryTasks2021\cmake-build-debug\bin\gtestd.dll
#  - C:\lib\install\opencv\x64\vc16\bin\opencv_world451d.dll
#
# 10) Launch test_sift - should work :)
