[英]Cmake link library target link error
Hi I have problem with linkg Glfw and other libraries using cmake. 嗨,我对使用cmake的linkg Glfw和其他库有问题。 From command line i compile like this
从命令行我这样编译
g++ main.cpp -lGL -lGLU -lGLEW -lglfw
But I wanted to use cmake for compiling. 但是我想使用cmake进行编译。 I tried to use target_linkg_libraries but this produce error
我尝试使用target_linkg_libraries,但这会产生错误
CMake Error at CMakeLists.txt:18 (target_link_libraries): Cannot specify link libraries for target "GL" which is not built by this
CMakeLists.txt:18(target_link_libraries)的CMake错误:无法为目标“ GL”指定链接库,该链接库不是由此库构建的
project.项目。
I tried do this using add definitions. 我尝试使用添加定义来做到这一点。 I dont see error but this don't link libraries.
我没有看到错误,但这没有链接库。
cmake_minimum_required (VERSION 2.6)
project (test)
find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
ADD_DEFINITIONS(
-lGL
-lGLU
-lGLEW
-lglfw
)
add_executable(test.out
main.cpp
)
target_link_libraries(GL GLU GLEW glfw)
The syntax for target_link_libraries
is: target_link_libraries
的语法为:
target_link_libraries(your_executable_name libraries_list)
And you don't have to add add_definition
statements ( target_link_libraries
adds this options) 而且你不必添加
add_definition
报表( target_link_libraries
添加此选项)
There are also some useful variables provided by OpenGL and GLEW packages. OpenGL和GLEW软件包还提供了一些有用的变量。
Your CMakeLists.txt should be like: 您的CMakeLists.txt应该类似于:
cmake_minimum_required (VERSION 2.6)
project (test)
find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
include_directories(${OPENGL_INCLUDE_DIR} ${GLEW_INCLUDE_DIRS})
add_executable(test
main.cpp
)
target_link_libraries(test ${OPENGL_LIBRARIES} ${GLEW_LIBRARIES})
One important detail to keep in mind is to place the target_link_libraries
after the add_executable
(or add_library
) line. 记住一个重要的细节是把
target_link_libraries
后 add_executable
(或add_library
)线。
