Firstly, I have installed MinGW from https://sourceforge.net/projects/mingw/files/ and the mingw32-gcc-g++ and mingw32-gcc-objs with it. I have added C:\MinGW\bin to my path.
Secondly, I have installed Git for windows (not really important, the result is the same on cmd.exe).
Thirdly, I have installed the complete package "make" with http://gnuwin32.sourceforge.net/packages/make.htm
After that, I have installed cmake 3.5.1 with the .msi.
But when I run cmake ../src
the result is :
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:5 (project):
No CMAKE_C_COMPILER could be found.
CMake Error at CMakeLists.txt:5 (project):
No CMAKE_CXX_COMPILER could be found.
-- Configuring incomplete, errors occurred!

See also "C:/Users/pauka/Dropbox/ETUDE/SRI/S8/STA_Stage/sources/tests/bin/CMakeFiles/CMakeError.log".
So cmake can't find gcc or g++. But when I run gcc -version, the output is good... What should I configure for cmake ?
My CMakeLists.txt is :
# Ajustez en fonction de votre version de CMake
cmake_minimum_required (VERSION 2.8)
# Nom du projet
project (main)
find_package (OpenCV REQUIRED)
# Exécutable "main", compilé à partir du fichier main.cpp
add_executable (tracking_color tracking_color.cpp)
add_executable (feuille feuille.cpp)
add_executable (detect_circles detect_circles.cpp)
add_executable (segmentation segmentation.cpp)
add_executable (watershed_perso watershed_perso.cpp)
add_executable (main main.cpp utils.h)
add_executable (info_coins info_coins.cpp)
# main sera linké avec les bibliothèques d'OpenCV
target_link_libraries (tracking_color ${OpenCV_LIBS})
target_link_libraries (feuille ${OpenCV_LIBS})
target_link_libraries (detect_circles ${OpenCV_LIBS})
target_link_libraries (segmentation ${OpenCV_LIBS})
target_link_libraries (watershed_perso ${OpenCV_LIBS})
target_link_libraries (info_coins ${OpenCV_LIBS})
target_link_libraries (main ${OpenCV_LIBS})

Ok, shame on me,
I had to restart my computer and select "MinGW Makefiles"
in the CMake GUI. Click Configure
, and after that Generate
.
Next, you must not use Git for windows
because there is sh.exe
and it's a cmake bug.
PS: to use OpenCV, you must compile it :
cd C:\opencv
mkdir my_build
cd my_build
cmake -G "MinGW Makefiles" ../sources
mingw32-make # took 2 hours on my computer
and next add, C:\opencv\my_build
and C:\opencv\my_build\bin
to the system path.

Maybe not the best answer but get things going. Install Bash On Ubuntu On Windows
and install cmake and make using sudo apt-get install cmake
and sudo apt-get install build-essential
if you don't already have them installed. However, Bash On Ubuntu On Windows
only comes with Windows 10
and for accessing a specific drive you should use /mnt/c
instead of C:\
Follow this official tutorial to install Bash On Ubuntu On Windows
.
mona@DESKTOP-0JQ770H:/mnt/c$ cmake -version
cmake version 2.8.12.2
mona@DESKTOP-0JQ770H:/mnt/c$ make -version
GNU Make 3.81

Additionally, of course you can install git in Bash On Ubuntu On Windows
sudo apt-get install git
mona@DESKTOP-0JQ770H:/mnt/c$ git --version
git version 1.9.1
though I don't suggest using a Linux-based git for pushing to github for a Windows specific SDK/code. I would still stick to Git Bash for dealing with git.
*I used to use CMAKE GUI for dealing with CMake in Windows 10 and then port my stuff to Visual Studio. That is also a neat solution depending on your codebase.

You can try setting manually the cxx path, see CMAKE_C_COMPILER from link which tells you more or less link this:
CXX=C:\path\to\g++ cmake ..
But, I would recommend you to see why cmake doesn't recognize your cxx compiler. I would double check your environment paths.
