+### Compiling
+
+I've a preference for compiling libraries by hand, mainly for backward compatibility, but I recommend using Conan packages manager (https://conan.io) for simplicity. (**Don't forget git submodules**)
 
 ```shell
-cmake .
-make
-make install
+conan install . -of build -b missing -s build_type=Release -o tools=True -pr:b=default -pr:h=default
+cmake --preset conan-release -G "Unix Makefiles"
+cmake --build --preset conan-release
 ```
 
-On Windows system, I can suggest you to use Conan support to help you with dependencies:
+On Windows environment, you can use MinGW `-G "MinGW Makefiles"` or Ninja `-G "Ninja"` as CMake generator.
 
-```shell
-mkdir build
-cd build
-conan install .. --build=missing
-cmake .. -G "MinGW Makefiles"
-make
-```
+### Compiling (HARDCORE)
 
-If you want to do it manually without Conan support, you will probably need to specify the dependency flags for CMake. Ex:
+If you want to do it manually without Conan, you will probably need to specify the dependency flags for CMake. Ex:
 
-`cmake.exe -D"ZLIB_INCLUDE_DIR=zlib/1.2.11/include" -D"ZLIB_LIBRARY=zlib/1.2.11/lib/libzlib.dll.a" -D"PNG_PNG_INCLUDE_DIR=libpng/1.6.37/include" -D"PNG_LIBRARY=libpng/1.6.37/lib/libpng.dll.a" . -G "MinGW Makefiles"`

-We can also use cross-compilation (after installing `mingw64` and `cmake` packages on your distrib):
-
-```shell
-mkdir build && cd build
-cmake -DGNU_HOST=x86_64-w64-mingw32 \
-	-DCMAKE_TOOLCHAIN_FILE=../cmake/mingw_cross_toolchain.cmake \
-	-D"ZLIB_INCLUDE_DIR=zlib/1.2.11/include" \
-	-D"ZLIB_LIBRARY=zlib/1.2.11/lib/libzlib.dll.a" \
-	-D"PNG_PNG_INCLUDE_DIR=libpng/1.6.37/include" \
-	-D"PNG_LIBRARY=libpng/1.6.37/lib/libpng.dll.a" \
-	..
-cmake --build .
-```
+I've tested cross-compilation too, but since I want to check that Conan is working properly at each release, I've integrated it into the Jenkins flow using Conan for the cross-abstraction.
