Note the updated usage requirements!

SFML >= 2.5.0
ImGui >= 1.68

This release greatly improves CMake and build support:

• Added versioning to CMake
• Added better install rules
• You can now easily link to ImGui-SFML - just do this:

find_package(ImGui-SFML REQUIRED)
target_link_libraries(my_target PRIVATE ImGui-SFML::ImGui-SFML)

• Can now build ImGui-SFML as shared library
• Can now provide path and name to custom imconfig if you don't want to use default imconfig-SFML.h
• Fixed some warnings on some compiers
• Check ImGui and SFML version in CMake

This release doesn't bring new features, but it's the first release which has proper version in CMake + it's just so good, it's a shame not to name it "2.0".

Semantic versioning will be used for future releases.
