CMake使用小结
指定本地库的位置
set(Qt5_DIR "path")
list(APPEND CMAKE_PREFIX_PATH ${Qt5_DIR})
设置编译输出的路径
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_DEBUG ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_DEBUG ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_RELEASE ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE ${CMAKE_BINARY_DIR}/bin)
file(GLOB headers *.h *.hpp)
file(GLOB srcs *.cpp)
add_executable(${app_name} ${headers} ${srcs} )
target_link_libraries(${app_name} ...)
file使用
file({GLOB | GLOB_RECURSE} <out-var> [...] [<globbing-expr>...])
file(RENAME <oldname> <newname>)
file({REMOVE | REMOVE_RECURSE } [<files>...])
file(MAKE_DIRECTORY [<dir>...])
file({COPY | INSTALL} <file>... DESTINATION <dir> [...])
file(COPY E:\\VSProject\\Surface\\build\\bin\\Debug\\Surface.exe DESTINATION C:\\Surface)
execute_process使用
execute_process(COMMAND windeployqt.exe E:\\VSProject\\Surface\\build\\bin\\Debug\\Surface.exe --dir E:\\VSProject\\Surface\\build\\bin\\Debug RESULT_VARIABLE ret)
添加一些基本的库
Boost
find_package(Boost COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})
target_link_libraries(${app_name} ${Boost_LIBRARIES})
Qt
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
file(GLOB ui_files *.ui)
file(GLOB resource_files *.qrc)
//在配置lib或exe时需要将resource 文件和 ui 文件添加进去
//add_executable(${app_name} ${headers} ${ui_files} ${resource_files})
find_package(Qt5 COMPONENTS Core Gui Widgets REQUIRED)
target_link_libraries(${app_name} Qt5::Core Qt5::Gui Qt5::Widgets)
VTK
find_package(VTK REQUIRED)
include_directories(${VTK_INCLUDE_DIRS})
//${VTK_LIBRARIES}
PCL
find_package(PCL 1.8 REQUIRED COMPONENTS common features filters kdtree ml octree registration io segmentation visualization)
include_directories(${PCL_INCLUDE_DIRS})
add_definitions(${PCL_DEFINITIONS})
//${PCL_LIBRARIES}
CMAKE_PREFIX_PATH是以分号分隔的列表，供find_package(), find_program(), find_library(), find_file()和find_path()使用，初始为空。
CMAKE_MODULE_PATH是以分号分隔的列表，供include()或 find_package()使用。初始为空。
两者的选择，优先使用CMAKE_PREFIX_PATH
CMAKE_BINARY_DIR 编译路径
CMAKE_CURRENT_BINARY_DIR 编译路径
CMAKE_SOURCE_DIR源文件的根路径
CMAKE_CURRENT_SOURCE_DIR 当前源文件路径
CMAKE_SHARED_LIBRARY_SUFFIX共享库的后缀
CMAKE_SHARED_LIBRARY_PREFIX共享库的前缀
CMAKE_EXECUTABLE_SUFFIX 可执行程序后缀
CMAKE_INCLUDE_PATH 头文件包含目录
CMAKE_LIBRARY_PATH 库文件包含目录
if (MSVC)
set(CompilerFlags
CMAKE_CXX_FLAGS
CMAKE_CXX_FLAGS_DEBUG
CMAKE_CXX_FLAGS_RELEASE
CMAKE_C_FLAGS
CMAKE_C_FLAGS_DEBUG
CMAKE_C_FLAGS_RELEASE
)
foreach(CompilerFlag ${CompilerFlags})
string(REPLACE "/MD" "/MT" ${CompilerFlag} "${${CompilerFlag}}")
endforeach()
endif(MSVC)
