cmake: add curl library path The `PKG_CHECK_MODULES` function searches a pkg-config module and then proceeds to set various variables containing information on how to link to the library. In contrast to the `FIND_PACKAGE` function, the library path set by `PKG_CHECK_MODULES` will not necessarily contain linking instructions with a complete path to the library, though. So when a library is not installed in a standard location, the linker might later fail due to being unable to locate it. While we already honor this when configuring libssh2 by adding `LIBSSH2_LIBRARY_DIRS` to the link directories, we fail to do so for libcurl, preventing us to build libgit2 on e.g. FreeBSD. Fix the issue by adding the curl library directory to the linker search path.
