The general signature is:find_library (VARname | NAMES name1 [name2 ...] [NAMES_PER_DIR][HINTS path1 [path2 ... ENV var]][PATHS path1 [path2 ... ENV var]][PATH_SUFFIXES suffix1 [suffix2 ...]][DOC cache documentation string][NO_DEFAULT_PATH][NO_CMAKE_ENVIRONMENT_PATH][NO_CMAKE_PATH][NO_SYSTEM_ENVIRONMENT_PATH][NO_CMAKE_SYSTEM_PATH][CMAKE_FIND_ROOT_PATH_BOTH |ONLY_CMAKE_FIND_ROOT_PATH |NO_CMAKE_FIND_ROOT_PATH]) 例子如下FIND_LIBRARY(RUNTIME_LIB rt /usr/lib /usr/local/lib NO_DEFAULT_PATH)cmake会在目录中查找如果所有目录中都没有值RUNTIME_LIB就会被赋为NO_DEFAULT_PATH 4. 添加需要链接的库文件路径LINK_LIBRARIES 语法link_libraries(library1 debug | optimized library2 ...) # 直接是全路径
link_libraries(“/home/server/third/lib/libcommon.a”)
# 下面的例子只有库名cmake会自动去所包含的目录搜索
link_libraries(iconv)# 传入变量
link_libraries(${RUNTIME_LIB})
# 也可以链接多个
link_libraries(/opt/MATLAB/R2012a/bin/glnxa64/libeng.so /opt/MATLAB/R2012a/bin/glnxa64/libmx.so)可以链接一个也可以多个中间使用空格分隔. 5. 设置要链接的库文件的名称TARGET_LINK_LIBRARIES 语法target_link_libraries(target [item1 [item2 [...]]] [[debug|optimized|general] item] ...) # 以下写法都可以
target_link_libraries(myProject comm) # 连接libhello.so库默认优先链接动态库
target_link_libraries(myProject libcomm.a) # 显示指定链接静态库
target_link_libraries(myProject libcomm.so) # 显示指定链接动态库# 再如
target_link_libraries(myProject libcomm.so) #这些库名写法都可以。
target_link_libraries(myProject comm)
target_link_libraries(myProject -lcomm) 6. 为工程生成目标文件 语法add_executable(name [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] source1 [source2 ...])简单的例子如下add_executable(demo main.cpp ) 7. 最后贴一个完整的例子 cmake_minimum_required (VERSION 2.6)INCLUDE_DIRECTORIES(../../thirdparty/comm)FIND_LIBRARY(COMM_LIB comm ../../thirdparty/comm/lib NO_DEFAULT_PATH)
FIND_LIBRARY(RUNTIME_LIB rt /usr/lib /usr/local/lib NO_DEFAULT_PATH)link_libraries(${COMM_LIB} ${RUNTIME_LIB})ADD_DEFINITIONS(
-O3 -g -W -Wall-Wunused-variable -Wunused-parameter -Wunused-function -Wunused-Wno-deprecated -Woverloaded-virtual -Wwrite-strings-D__WUR -D_REENTRANT -D_FILE_OFFSET_BITS64 -DTIXML_USE_STL
)add_library(lib_democmd.cppglobal.cppmd5.cpp
)link_libraries(lib_demo)
add_executable(demomain.cpp
)# link library in static mode
target_link_libraries(demo libuuid.a)另外使用cmake生成makefile之后make edit_cache可以编辑编译选项 不熟悉的命令可以去查找文档贴个cmake3.0官方帮助文档地址https://cmake.org/cmake/help/v3.0/index.html 转载于:https://www.cnblogs.com/wangshuyi/p/11405347.html
