Unable to add_subdirectory (cucumber-cpp) because include directory is not setup properly

[ghost]

Steps to Reproduce

Clone into sub-directory import and use add_subdirectory (import/cucumber-cpp). Build fails:

...

Cucumber C++ Include directory resolved as project/include But it should be project/import/cucumber-cpp/include

Possible Solution

Change this:

https://github.com/cucumber/cucumber-cpp/blob/f79990879a3c2eea288de6efeefc4008937300cc/src/CMakeLists.txt#L75

to this:

        $<BUILD_INTERFACE:${CUKE_INCLUDE_DIR}>

Use case

CMakeLists.txt

FetchContent_Declare (cucumber_cpp
    GIT_REPOSITORY https://github.com/cucumber/cucumber-cpp.git
    GIT_TAG        v0.5
)

FetchContent_GetProperties (cucumber_cpp)
if (NOT cucumber_cpp_POPULATED)

    FetchContent_Populate (cucumber_cpp)

    set (CUKE_DISABLE_GTEST         ON CACHE BOOL "Don't build Google Test")
    set (CUKE_DISABLE_QT            ON CACHE BOOL "Don't build Qt")
    set (CUDE_DISABLE_UNIT_TESTS    ON CACHE BOOL "Don't build unit tests")
    set (CUKE_DISABLE_E2E_TESTS     ON CACHE BOOL "Don't build end-to-end tests")

    add_subdirectory (
        ${cucumber_cpp_SOURCE_DIR}
        ${cucumber_cpp_BINARY_DIR}
    )

endif ()
