1.3 上述问题修改完成后再次进行编译

make

2. 成功后在Dist文件夹下会生成静态链接、动态链接以及头文件

#============================================================================================
# CMakeLists.txt
#============================================================================================

set(FreeImage_INCLUDE_DIR "/path/to/FreeImage-3.17.0/Dist")

include_directories( ${FreeImage_INCLUDE_DIRS} )

find_library(FreeImage_LIBS freeimage-3.17.0 ${FreeImage_DIR})

target_link_libraries( executable_name ${FreeImage_LIBS} )
