Implicit linker search path detected for language
Compilers typically pass directories containing language runtime libraries and default library search paths when they invoke a linker. These paths are implicit linker search directories for the compiler's language. CMake automatically detects these directories for each language and reports the results in this variable.
When a library in one of these directories is given by full path to target_link_libraries CMake will generate the
-l<name> form on link lines to ensure the linker searches its implicit directories for the library. Note that some toolchains read implicit directories from an environment variable such as
LIBRARY_PATH so keep its value consistent when operating in a given build tree.
