I think you should either use the full file name, e.g. libClp.so or just use Clp. See https://cmake.org/cmake/help/latest/command/find_library.html

In a CMakeLists.txt I have the following lines of code: # with this the user will be asked for a path that has then # lib64 other subdirectories that are specified below FIND_PATH(CLP_DIR libClp) SET(CLP_LIB ${CLP_DIR}/lib64) # after the user specified CLP_DIR this shows what is expected: # the full path to the libraries, but... message(AUTHOR_WARNING ${CLP_LIB}) # with the following I think I cannot indicate more clearly where the libraries actually are: FIND_LIBRARY(CLP_LIBRARY NAMES libClp PATHS ${CLP_LIB} NO_DEFAULT_PATH) FIND_LIBRARY(COINUTILS_LIBRARY NAMES libCoinUtils PATHS ${CLP_LIB} NO_DEFAULT_PATH) FIND_LIBRARY(OSI_LIBRARY NAMES libOsi PATHS ${CLP_LIB} NO_DEFAULT_PATH) FIND_LIBRARY(OSICLP_LIBRARY NAMES libOsiClp PATHS ${CLP_LIB} NO_DEFAULT_PATH) # ...here everything comes as -NOTFOUND message(AUTHOR_WARNING ${CLP_LIBRARY}) message(AUTHOR_WARNING ${COINUTILS_LIBRARY}) message(AUTHOR_WARNING ${OSI_LIBRARY}) message(AUTHOR_WARNING ${OSICLP_LIBRARY}) A dir for the indicated directory shows the following files: -rwxrwxrwx 1 cornelis users 907 8.

Nov 18:37 pkgconfig so the libraries are obviously there! Questions: What am I doing wrong? What did I possibly misunderstand regarding the find_library command? Thanks for any helpful hints!
