Specify Linker Options for Executables and Shared Libraries in CMake
Using target_link_options to Set Linker Options
To set linker options for executables and shared libraries in CMake, you can utilize the target_link_options command. This command allows you to specify options that will be passed to the linker during the linking phase of the build process.
Example Syntax
target_link_options(<target> PUBLIC <options>) target_link_options(<target> PRIVATE <options>) target_link_options(<target> INTERFACE <options>)
The <target> parameter specifies the target that the linker options should be applied to.
The PUBLIC, PRIVATE, and INTERFACE keywords specify the scope of the linker options. PUBLIC options are visible to all targets that depend on the target being linked, PRIVATE options are only visible to the target being linked, and INTERFACE options are only visible to targets that inherit from the target being linked.
The <options> parameter specifies the linker options that should be passed to the linker. These options can be any valid linker option supported by your compiler.
Using target_link_directories to Specify Search Paths for Libraries
To specify search paths for libraries that are not found in standard locations, you can use the target_link_directories command. This command allows you to add additional directories to the linker's search path, which can help it find the libraries you need to link against.
Example Syntax
target_link_directories(<target> PUBLIC <directories>) target_link_directories(<target> PRIVATE <directories>) target_link_directories(<target> INTERFACE <directories>)
The <target> parameter specifies the target that the search paths should be applied to.
The PUBLIC, PRIVATE, and INTERFACE keywords specify the scope of the search paths. PUBLIC paths are visible to all targets that depend on the target being linked, PRIVATE paths are only visible to the target being linked, and INTERFACE paths are only visible to targets that inherit from the target being linked.
The <directories> parameter specifies the directories that should be added to the linker's search path. These directories can be absolute or relative to the current working directory.
