ITK cmake 添加多个基于ITK的可执行文件

1、CMakeLists.txt

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(testfilter)
set(ITK_DIR D:/ProgramFiles/ITK-5.2/lib/cmake/ITK-5.2)

FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})

file(GLOB_RECURSE mains ${CMAKE_CURRENT_SOURCE_DIR} *.cpp)
message(STATUS ${mains})
foreach(mainfile IN LISTS mains)
    # Get file name without directory
    get_filename_component(mainname ${mainfile} NAME_WE)
    add_executable(${mainname} ${mainfile})
    target_link_libraries (${mainname} ${ITK_LIBRARIES})
endforeach()

2、get_filename_component 用法

get_filename_component

DIRECTORY = Directory without file name
NAME      = File name without directory
EXT       = File name longest extension (.b.c from d/a.b.c)
NAME_WE   = File name with neither the directory nor the longest extension
LAST_EXT  = File name last extension (.c from d/a.b.c)
NAME_WLE  = File name with neither the directory nor the last extension
PATH      = Legacy alias for DIRECTORY (use for CMake <= 2.8.11)
