Installing #147

Closed t0mpl closed 4 years ago

t0mpl commented 4 years ago

Hi everyone, Sorry i'm quite new with C++ and i can't figure out how to install this library

i've tried add_library(daw STATIC) target_include_directories(daw PUBLIC ${PROJECT_SOURCE_DIR}/external/daw) add_library(third_party STATIC) target_include_directories(third_party PUBLIC ${PROJECT_SOURCE_DIR}/external/third_party) target_link_libraries(${LIBRARY_NAME} PUBLIC doctest daw third_party)

but in my main.cpp i get this error when "make" fatal error: daw/json/daw_json_link.h: No such file or directory 29 | #include "daw/json/daw_json_link.h"

Does anyone have any idea how to install it easily?

With the old version, one needed to clone the three repos and have them in the include path. In dev, and in the last prerelease https://github.com/beached/daw_json_link/releases/tag/v1.9.2 which should be stable and is nearing the v2.0 release one can use cmake's fetchcontent or do an install of the library. I would recommend using the v1.9.2. linked above as it's only deficiency compared to the v1 is the documentation isn't fully updated. It does include an extensive set of test/example files in tests though.

If you want v2. and the prerelease for the way to include in your cmake project is to

include( FetchContent )
FetchContent_Declare(
        daw_json_link
        GIT_REPOSITORY https://github.com/beached/daw_json_link
        GIT_TAG v1.9.2
)
FetchContent_MakeAvailable(daw_json_link)

then in your target_link_libraries it's just

target_link_libraries( MyTarget daw::json_link )

And the include paths would be set for everything needed and cmake will pull in the dependencies needed

The release branch is now at v2. So the above instructions can be 

include( FetchContent )
FetchContent_Declare(
        daw_json_link
        GIT_REPOSITORY https://github.com/beached/daw_json_link
)
FetchContent_MakeAvailable(daw_json_link)

then in your target_link_libraries it's just


target_link_libraries( MyTarget daw::json_link )

@beached Couldnt expect a better answer, thank you.

FYI, When installing it, it seemed that Cmake was by default looking for master branch.

include( FetchContent ) FetchContent_Declare( daw_json_link GIT_REPOSITORY https://github.com/beached/daw_json_link GIT_TAG release ) FetchContent_MakeAvailable(daw_json_link)

specifying the branch helped.

Thanks, I'll update the docs. Too bad that cmake doesn't use the default branch.
