How to include externally using CMake

[ferdymercury]

Hello, thanks for the repository!

Is there a clean way to include it from other projects, using find_package(Modbus) or something similar, instead of hard-coding the paths? (I installed it using apt)

If yes, could this info be added to the README ?

Ok, I managed the following, using https://github.com/ferdymercury/cmake-modules/blob/main/FindModbus.cmake:

find_package(Modbus REQUIRED)
set (modbuspp_DIR "/usr/local/lib/modbuspp/cmake/" CACHE STRING "modbuspp cmake folder")
find_package(modbuspp REQUIRED)

add_executable(foo foo.cpp)
target_compile_options(foo PRIVATE)
target_include_directories(foo PRIVATE ${MODBUS_INCLUDE_DIR} ${MODBUSPP_INCLUDE_DIRS})
target_link_libraries(foo PUBLIC ${MODBUSPP_LIBRARIES})
add_test(
    NAME foo
    COMMAND foo ?
)

I think it would be nicer if the CMake file would automatically define the interface_directories and libraries to include, instead of having to apply those manually in your targets.
