Hi Denis, There are definitely cases where you do want to create a statically linked executable; for example when running on a massively parallel diskless system -- you don't want thousands of compute nodes to load a shared library over some NFS link.
Anyway, the real problem with find_library() is, when you have a shared library installed, but not the associated static library. In that case, the linker will choke while creating a statically linked executable, because it cannot find the library it needs. I guess the only way to solve this is to manually set CMAKE_FIND_LIBRARY_SUFFIXES, like FindBoost.cmake does. I wish there were a more generic, platform-independent way to do this. Maybe worth a feature request? Best regards, Marcel Loose.
