CMake : link a produced library?

Find_library() is a little more than the name suggests, it not only finds the path to a (preinstalled) lib, but often also prepares a lot of variables and functions. Also find_library() only works with specific library modules, which reside in the cmake/share directory.

Find_library() is a little more than the name suggests, it not only finds the path to a (preinstalled) lib, but often also prepares a lot of variables and functions. Also find_library() only works with specific library modules, which reside in the cmake/share directory. When you build your own library you have to add it to the CMakeLists.

Txt with the add_library() command, which works exactly like the add_executable() command. When you have done that, you can actually add the library to the executable using the target_link_libraries() command. To sum it up: add_library(myLib libsourceA.

C libSourceB. C) add_executable(myProgram prgsourceA. C prgsourceB.

C) target_link_libraries(myProgram myLib) You actually don't have to know or specify the exact location of the library-file, cmake will manage that for you.

1 find_library simply finds a library file and returns its full path in the named variable you give as a parameter. It does not "often also prepares a lot of variables and functions" -- you might be thinking of "find_package" which loads a Find*. Cmake file or a project-Config.

Cmake file and often does have a side effect of setting many related variables. – DLRdave Aug 20 at 16:13.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
