BUILD_INTERFACE fatal error: 'hiredis/hiredis.h' file not found

[Portgas-D-Asce]

a strange thing in

TARGET_INCLUDE_DIRECTORIES(hiredis PUBLIC $<INSTALL_INTERFACE:include> $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>)

in INSTALL_INTERFACE, using #include <hiredis/hiredis.h> is ok

in BUILD_INTERFACE, I have to change it to #include <hiredis.h>

keep them same maybe better

Can you provide some more context? What's failing exactly?

Can you provide some more context? What's failing exactly?

firstly, fetch hiredis into my project and use it by target_link_libraries

find_package(hiredis 1.2.0 QUIET)
if (NOT hiredis_FOUND)
    include(FetchContent)
    fetchcontent_declare(hiredis
        GIT_REPOSITORY https://github.com/redis/hiredis.git
        GIT_TAG v1.2.0
        SOURCE_DIR ${CMAKE_BINARY_DIR}/_deps/hiredis
    )
    fetchcontent_makeavailable(hiredis)
    if(NOT hiredis_POPULATED)
        message(FATAL_ERROR "fetch hiredis failed!")
    endif ()
endif ()

target_link_libraries(redis_pool
    PUBLIC
    hiredis::hiredis
)

then include <hiredis/hireids.h> in my header file，but clion complains "hiredis/hiredis.h file not found"，so print redis::redis's properties

include(CMakePrintHelpers)
cmake_print_properties(
    TARGETS
    hiredis::hiredis
    PROPERTIES
    INTERFACE_INCLUDE_DIRECTORIES
)
# Properties for TARGET hiredis::hiredis:
#    hiredis::hiredis.INTERFACE_INCLUDE_DIRECTORIES = "$<INSTALL_INTERFACE:include>;$<BUILD_INTERFACE:/xx/Project/cmake-build-debug/_deps/hiredis>"

the reason why clion complains in BUILD_INTERFACE is obvious. it's why

• in INSTALL_INTERFACE use include <hiredis/hireids.h>
• in BUILD_INTERFACE have to use include <hireids.h>

in most of others libraries, both of them are same and better for using.
