How to use CMake to compile with ROOT libraries

Dear experts

I’m new with CMake, I wrote one .cxx and .hxx file and the .hxx contains like:

#include <TFile.h>

And in my CMakeLists.txt it’s like:

cmake_minimum_required(VERSION 3.3 FATAL_ERROR)
project(CRTTracking)
set(CMAKE_CXX_STANDARD 14)

find_package(ROOT REQUIRED)


add_executable(CRTTracking ${CMAKE_CURRENT_SOURCE_DIR}/src/CRTTracking.cxx)
target_include_directories(CRTTracking PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/src)
target_link_libraries(CRTTracking ${ROOT_LIBRARIES})

install(TARGETS CRTTracking
        DESTINATION ${CMAKE_CURRENT_SOURCE_DIR}/bin)

But when I make the files the error occurred:

In file included from /Users/siyuan/Physics/comet/crt/tracking/src/CRTTracking.cxx:1:
/Users/siyuan/Physics/comet/crt/tracking/src/CRTTracking.hxx:4:10: fatal error: 'TFile.h' file not found
#include <TFile.h>

What did I do wrong in CMakeLists.txt?

Please read tips for efficient and successful posting and posting code

Try with:

cmake_minimum_required(VERSION 3.3 FATAL_ERROR)
project(CRTTracking)
find_package(ROOT REQUIRED)

set(CMAKE_CXX_FLAGS "${ROOT_CXX_FLAGS}")
include(${ROOT_USE_FILE})

add_executable(CRTTracking ${CMAKE_CURRENT_SOURCE_DIR}/src/CRTTracking.cxx)
target_include_directories(CRTTracking PUBLIC 
                           ${CMAKE_CURRENT_SOURCE_DIR}/src ${ROOT_INCLUDE_DIRS})
target_link_directories(${ROOT_LIBRARY_DIR})
target_link_libraries(CRTTracking ${ROOT_LIBRARIES})

install(TARGETS CRTTracking
        DESTINATION ${CMAKE_CURRENT_SOURCE_DIR}/bin)
