Why should I use Conan package management? 

Why use Conan Package management ？

• Easier to manage any transient dependency - define the dependency and Conan manages the dependencies with exactly the correct package versions.
• Easier to manage any temporary dependencies - Define dependencies ,Conan Manage dependencies with the correct package version .
• Improved modularity - Download only the packages your project needs, nothing else.
• Improved modularity — Download only the packages required for the project , Do not download other packages .
• Manage external libraries - Conan helps in using dependencies to any other libraries as long as you have the Conan recipe 
• Manage external libraries - As long as you have Conan formula ,Conan Can help you use dependencies on any other library
• Custom build configurations - Didn't you find the binaries/build configuration you needed? Just edit the provided build profiles for your needs and pass "--build" and Conan will build everything you need from sources (provided you have compilation tools in your environment). The built binaries are stored in your local Conan cache, from where the binaries can be then easily re-used.
• Custom build configuration - You did not find the required binary / Generate configuration ？ Just edit the provided build profile and pass it along as you need it “-build”,Conan You'll build everything you need from the source code （ The premise is that there are compilation tools in your environment ）. The built binaries are stored locally Conan In cache , Where binaries can be easily reused .
• Conan caches the binaries locally so additional installations are faster.
• Conan caches binary files locally , For other installations faster .
